qcacld-3.0: Don't invoke QDF_BUG in case of timeout

Currently, when bus resume is triggred by host then host waits
for resume event from fw and in case of failure QDF_BUG is
triggered but QDF_BUG is triggred in case of timeout/fw doesn't
send resume event within 4 seconds which may cause unwanted
crash instead of self recovery.

Fix is not to invoke QDF_BUG in case of failure to avoid
unwanted crash instead of self recovery.
