bnxt_en: Decode and log "current fault" module events

[chandrakanth.patil_broadcom.com]

Summary

Firmware exposes the module's "current fault" status via the module_status field in HWRM_PORT_PHY_QCFG.
When a fault occurs, firmware generates a LINK_STATUS_CHANGE event.
The driver now checks the module_status for "current fault" on each such event and logs it for visibility.
