Shubhrajyoti Datta 77bad0ab1b serial: uartps: Move the spinlock after the read of the tx empty ...

commit 107475685a upstream.

Currently we are doing a read of the status register.
Move the spinlock after that as the reads need not be spinlock
protected. This patch prevents relaxing the cpu with spinlock held.
