Use error_is_set() only when necessary

error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out. Unnecessarily hard for
optimizers, static checkers, and human readers. Dumb it down to
obvious.

Gets rid of several dozen Coverity false positives....

pty_chr_timer first calls pty_chr_update_read_handler(), then clears

though. pty_chr_update_read_handler might re-arm time timer, and the
new timer_tag gets overwitten in that case....
