Subject: bnxt_en: Check for zero dir entries in NVRAM.
From: Vasundhara Volam <vasundhara-v.volam@xxxxxxxxxxxx>
[ Upstream commit dbbfa96ad920c50d58bcaefa57f5f33ceef9d00e ]
If firmware goes into unstable state, HWRM_NVM_GET_DIR_INFO firmware
command may return zero dir entries. Return error in such case to
avoid zero length dma buffer request.
Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
