scsi: ufs: wait for a longer time for fDeviceInit to clear 



On some device, in some cases, the initialization time is
uncharacteristically long. This is within the standard which states
in section 13.4.6.1.2 (Dynamic Capacity Procedural Flow):
"The device initialization may take a time longer than normal
initialization..."
Therefore, making the loop pending on fDeviceInit to clear
longer.
