Bart Van Assche 681cc36083 IB/srp: Fix infinite loop when FMR sg[0].offset != 0 ...

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 8c4037b501 ("IB/srp: always avoid non-zero offsets
into an FMR").
