[PATCH] scsi: ufs: core: increase the NOP_OUT command timeout

[DooHyun Hwang]

It is found that is UFS device may take longer than 500ms(50ms * 10times)
to respond to NOP_OUT command.

The NOP_OUT command timeout was total 500ms that is from
a timeout value of 50ms(defined by NOP_OUT_TIMEOUT)
with 10 retries(defined by NOP_OUT_RETRIES)

This change increase the NOP_OUT command timeout to total 1000ms
by changing timeout value to 100ms(NOP_OUT_TIMEOUT)
