fatfs: fix build warning with 64k PAGE_SIZE
Annoying gcc warning:
fs/fat/inode.c: In function 'fat_fill_super':
fs/fat/inode.c:1222: warning: comparison is always false due to limited range of data type
Change it to compare with 4K instead of PAGE_CACHE_SIZE, as suggested
by OGAWA-san.
[FAT spec says: logical_sector_size should be 512, 1024, 2048 4096]
So, at least for now, we limit it to 4096.
