[PATCH] fat: fix sector print

[PATCH] fat: fix sector print

[Arnd Bergmann]

Printing a sector_t using %ld fails when that is a 64-bit type on
32-bit architectures:

fs/fat/inode.c: In function '__fat_get_block':
fs/fat/inode.c:163:9: error: format '%ld' expects argument of type 'long int', but argument 5 has type 'sector_t' {aka 'long long unsigned int'} [-Werror=format=]
         "invalid FAT chain (i_pos %lld, last_block %ld)",

The common workaround is to cast the number to a 64-bit type and print that
as %lld, that works in all configurations.

Fixes: mmotm ("fat: use fat_fs_error() instead of BUG_ON() in __fat_get_block()")
