storage: Need to also VIR_FREE(reg)

Browse Source 
Commit-id 'afc4631b' added the regfree(reg) to free resources alloc'd
during regcomp; however, reg still needed to be VIR_FREE()'d. The call
to regfree() also didn't account for possible NULL value.  Reformatted
the call to be closer to usage.
(cherry picked from commit 71da3b66a8)

Backported to 0.9.12 with afc4631b and its revert skipped.
