Instead of calling qla2x00_fcport_event_handler() and letting the switch
statement inside that function decide which other function to call, call
the latter function directly. Remove the event member from the event_arg
structure because it is no longer needed. Remove the
qla_handle_els_plogi_done() function because it is never called.

The LIO core requires that the target driver callback functions
.queue_data_in() and .queue_status() call target_put_sess_cmd() or
transport_generic_free_cmd(). These calls may happen synchronously or
asynchronously. Make sure that one of these LIO functions is called in case
a command has been aborted. This patch avoids that the code for removing a
session hangs due to commands that do not make progress.

Since no definitions or declarations from <linux/blk-mq.h> are used in the

Instead of allocating a struct srb dynamically from inside .queuecommand(),
set qla2xxx_driver_template.cmd_size such that struct scsi_cmnd and struct
srb are contiguous. Do not call QLA_QPAIR_MARK_BUSY() /
QLA_QPAIR_MARK_NOT_BUSY() for SRBs associated with SCSI commands. That is
safe because scsi_remove_host() is called before queue pairs are deleted
and scsi_remove_host() waits for all outstanding SCSI commands to finish.

Since all pointers passed to the srb_t.done() and srb_t.free() functions
have type srb_t, change the type of the first argument of these functions
from void * into struct srb *. This allows the compiler to verify the
argument types for these functions. This patch does not change any
functionality.

This change makes it easier to detect qla24xx_read_flash_data() failures
and also to handle such failures. This change does not modify the behavior
of the driver since all callers ignore the qla24xx_read_flash_data()
return value.

Introduce the be_id_t and le_id_t data types for Fibre Channel source and
destination ID formats supported by the firmware instead of using an
uint8_t[3] array. Introduce functions for converting from and to the
port_id_t data types. This patch does not change the behavior of the
qla2xxx driver but improves source code readability and also allows the
compiler to verify the endianness of Fibre Channel IDs.

Such a timeout is a severe issue. Hence complain if waiting for pending
commands times out. This patch fixes a small bug: it modifies
qla82xx_chip_reset_cleanup() such that the "Done waiting" message is
reported if qla82xx_chip_reset_cleanup() succeeded instead of if that
function failed.
