[patch] fix invalid free() in HEAD's readlink.c

[Bernhard Fischer]

Hi,

Sorry, i overread that bug yesterday.

http://busybox.net/cgi-bin/viewcvs.cgi?rev=9542&view=rev
introduced RESERVE_CONFIG_BUFFER but forgot to use the proper cleanup
in the exit path.

This fixes the invalid free() call.

please apply (the stable branch doesn't seem to be affected),
Bernhard
