The macros do_each_path/while_each_path lead to a smatch warning:
drivers/infiniband/ulp/rtrs/rtrs-clt.c:1196 rtrs_clt_failover_req() warn: inconsistent indenting
drivers/infiniband/ulp/rtrs/rtrs-clt.c:2890 rtrs_clt_request() warn: inconsistent indenting
Also checkpatch complains:
ERROR: Macros with multiple statements should be enclosed in a do - while loop
The macros are used only in two places: for a normal IO path and for the
failover path triggered after errors.
Get rid of the macros and just use a for loop iterating over the list of
paths in both places. It is easier to read and also less lines of code.

When Block Device Layer is disabled, BLK_MAX_SEGMENT_SIZE is undefined.
The rtrs is a transport library and should compile independently of the
block layer. The desired max segment size should be passed down by the
user.
Introduce max_segment_size parameter for the rtrs_clt_open() call.
