IB/srp: Fix infinite loop when FMR sg[0].offset != 0
commit 681cc3608355737c1effebc8145f95c8c3344bc3 upstream.
Avoid that mapping an sg-list in which the first element has a
non-zero offset triggers an infinite loop when using FMR. This
patch makes the FMR mapping code similar to that of ib_sg_to_pages().
Note: older Mellanox HCAs do not support non-zero offsets for FMR.
See also commit 8c4037b501ac ("IB/srp: always avoid non-zero offsets
into an FMR").
