[PATCH 5/8] util/compatfd.c: Replaced a malloc with GLib's variant

[Mahmoud Mandour]

Replaced a malloc() call and its respective free() call with
GLib's g_try_malloc() and g_free().

Also, did slight styling changes that were producing
style errors when using the checkpatch.pl script against
the file.
