[PATCH][BZ #10246] glob() with GLOB_NOCHECK is returning a modified pattern sometimes.

[Ondřej Bílka]

Hi,

This bug was caused joining cases when we do not check for errors or
directory exists. A fix is simple, jump to code that handles no matches.

	[BZ #10246]
	* posix/glob.c (glob): Return correct value when GLOB_NOCHECK
	is specified.
