[PATCH] ns16550: fix poll handling regression
Prior to c/s 23811:f1349a968a5a LSR_THRE was checked only once, while
there it got promoted into the surrounding loop''s condition. Since that
bit may not clear for an extended period of time (i.e. when no new
output is generated), it must not be used in this way indefinitely.
