[PATCH 1/4 v2] nfs-utils: Fix potential memory leaks in idmap

[Alice Mitchell <ajmitchell@redhat.com>]

regex.c: regex_getpwnam() would leak memory if the name was not found.

nss.c: nss_name_to_gid() the conditional frees look like a potential
       memory leak, removed the unnecessary conditions.
