RDMA/bnxt_re: Return error for SRQ resize 

[ Upstream commit 3687b450c5f32e80f179ce4b09e0454da1449eac ]

SRQ resize is not supported in the driver. But driver is not
returning error from bnxt_re_modify_srq() for SRQ resize.

Fixes: 37cb11acf1 ("RDMA/bnxt_re: Add SRQ support for Broadcom adapters")
