I simplified dfaexec_main in bug#19252, but it was not enough. This
change additionally simplifies it. The change induces no semantic change.

Subject: [PATCH] dfa: more simplification of dfaexec_main
* src/dfa.c (dfaexec_main): Failure at an acceptable position and demand
to build state is unlikely. So go next loop without checking them after
a newline. This commit induces no semantic change.
