[PATCH net-next] bnxt_en: Fix build error for kernesl without RTC-LIB

[Michael Chan <michael.chan@broadcom.com>]

From: Rob Swindell <swindell@broadcom.com>

bnxt_hwrm_fw_set_time() now returns -EOPNOTSUPP when built for kernel
without RTC_LIB.  Setting the firmware time is not critical to the
successful completion of the firmware update process.
