scsi: ufs: Enable irq in err_handler



There's a chance that error handler is invoked with
IRQ's disabled. For instance, in case the resume fails
the state is changed to old state - meaning, the state
of the controller is reverted back to suspend.
This entails disabling the IRQ.

Thus, commands timeout during error-handling as well.
Hence, enable IRQs in error-handler before issuing
commands.
