Subject: [PATCH] storage: Fix memory leak with regfree(reg) call.

https://bugzilla.redhat.com/show_bug.cgi?id=906299

Although 'reg' was VIR_FREE()'d, a call to regfree(reg) was also required
to free resources alloc'd during regcomp.

(cherry picked from commit 71da3b66a8455faf8019effe3cf504a31f91f54a)
