RDS: IB: fix 'passing zero to ERR_PTR()' warning

Browse Source 
[ Upstream commit 5941923da29e84bc9e2a1abb2c14fffaf8d71e2f ]

Fix a static code checker warning:
 net/rds/ib_frmr.c:82 rds_ib_alloc_frmr() warn: passing zero to 'ERR_PTR'

The error path for ib_alloc_mr failure should set err to PTR_ERR.

Fixes: 1659185fb4d0 ("RDS: IB: Support Fastreg MR (FRMR) memory registration mode")
