scsi: ufs: Fix interrupt error message for shared interrupts
[ Upstream commit 6337f58cec030b34ced435b3d9d7d29d63c96e36 ]
The interrupt might be shared, in which case it is not an error for the
interrupt handler to be called when the interrupt status is zero, so don't
print the message unless there was enabled interrupt status.
