IB/SRP: Avoid using IB_MR_TYPE_SG_GAPS
Tests have shown that the following error message is reported when
using SG-GAPS registration with an mlx5 adapter:
scsi host1: ib_srp: failed RECV status WR flushed (5) for CQE ffff880bd4270eb0

scsi host1: ib_srp: failed FAST REG status memory management operation error (6) for CQE ffff880b92860138
Hence avoid using SG-GAPS memory registrations. Additionally,
always configure the blk_queue_virt_boundary() to avoid to trigger
a mapping failure when using adapters that support SG-GAPS (e.g.
mlx5).
Fixes: commit ad8e66b4a801 ("IB/srp: fix mr allocation when the device supports sg gaps")
Fixes: commit 509c5f33f4f6 ("IB/srp: Prevent mapping failures")
