fs/fat/inode.c: clean up string initializations (char[] instead of ch…

…ar *)

Initializations like 'char *foo = "bar"' will create two variables: a
static string and a pointer (foo) to that static string.  Instead 'char
foo[] = "bar"' will declare a single variable and will end up in shorter
assembly (according to Jeff Garzik on the KernelJanitor's TODO list).
