regex: fix match with possessive quantifier

Fix behaviour introduced in 70b673eb7, where regexps with
possessive quantifier("*+") didn't match.

* lib/regexec.c (set_regs): Pop if CUR_NODE has already been checked
only when we have a fail stack.

Fixes: 70b673eb7 ("regex: fix longstanding backref match bug")
