RDMA/bnxt_re: Return more meaningful error

[ Upstream commit 98647df0178df215b8239c5c365537283b2852a6 ]

When the HWRM command fails, driver currently returns -EFAULT(Bad
address). This does not look correct.

Modified to return -EIO(I/O error).

Fixes: cc1ec769 ("RDMA/bnxt_re: Fixing the Control path command and response handling")
Fixes: 65288a22ddd8 ("RDMA/bnxt_re: use shadow qd while posting non blocking rcfw command")
