fat: cleanup fat_parse_long() error handling
Coverity CID 2332 & 2333 RESOURCE_LEAK In fat_search_long() if fat_parse_long() returns a -ve value we return without first freeing unicode. This patch free's them on this error path. The above was false positive on current tree, but this change is more clean, so apply as cleanup.
