From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
Fix HWRM_VER_GET command to handle DEV_NOT_RDY state.
Driver should fail probe if the device is not ready.
Conversely, the HWRM_VER_GET poll after reset can safely
retry until the existing timeout is exceeded.
Fixes: 804e746c7b73 ("net/bnxt: add hardware resource manager init code")
