[PATCH] fs/fat/dir.c fix resource leak

["Darren Jenkins\\" <darrenrjenkins@gmail.com>]

G'day people,

Coverity CID 2332 & 2333 RESOURCE_LEAK


In fat_search_long() if fat_parse_long() returns a -ve value we return
without first freeing unicode and bufname.
This patch free's them on this error path.

Patch against linux-next commit 99be8ca04aa13c0ff10bbb3ba5f90676b050fcc6
Only compile tested
