[PATCH net-next v2 1/9] bnxt_en: Return -EROFS to user space, if NVM writes are not permitted.

[Michael Chan]

From: Vasundhara Volam <vasundhara-v.vo...@broadcom.com>

If NVRAM resources are locked, NVM writes are not permitted. In such
scenarios, firmware returns HWRM_ERR_CODE_RESOURCE_LOCKED error to
firmware commands.
