Subject: [PATCH] net/bnxt: check access denied for HWRM commands

[ upstream commit 6dc875ab5ff76377376906aa6d05d95ffd34b9f9 ]

Firmware can restrict access to certain resources in the hardware
depending on various factors. In such cases when the PMD tries to
configure these resources the firmware will return
HWRM_ERR_CODE_RESOURCE_ACCESS_DENIED error. Parse this and return
the standard EACCES error to the applications.

Fixes: 804e746c7b73 ("net/bnxt: add hardware resource manager init code")
