Andriy Gapon 0d2fd5b99c ns8250: use LSR_THRE instead of LSR_TEMT for checking tx flush 
LSR_TEMT bit is set if both transmit hold and shift registers are
empty, but the flush command flushes only the hold register.

While here, update the diagnostic message to report which registers
could not be flushed.
