scsi: target/iscsi: Reduce number of __iscsit_free_cmd() callers

Browse Source 
Instead of calling __iscsit_free_cmd() from inside iscsit_aborted_task() if
a command has been aborted and from inside iscsit_free_cmd() if a command
has not been aborted, call __iscsit_free_cmd() from inside
lio_release_cmd(). The latter function is namely called for all commands
once the reference count has dropped to zero.
