Fix bug in file system library 

When InitFileSystem() API is given EnumFileSystemTypeFat in argument,
the FAT file system is not initialized. This bug is discovered when
firmware update payload fails to load capsule from FAT partition via
shell interface.

Fixed #62 

TEST=Created FwuImage.bin and perform firmware update from SBL shell on
     UP2 board. Verified successful update and booting to Ubuntu 16.04
     from eMMC
