bcachefs: Fix -Wformat in bch2_bucket_gens_invalid()
When building bcachefs for 32-bit ARM, there is a compiler warning in
bch2_bucket_gens_invalid() due to use of an incorrect format specifier:
fs/bcachefs/alloc_background.c:530:10: error: format specifies type 'unsigned long' but the argument has type 'size_t' (aka 'unsigned int') [-Werror,-Wformat]
529 | prt_printf(err, "bad val size (%lu != %zu)",
| ~~~
| %zu
530 | bkey_val_bytes(k.k), sizeof(struct bch_bucket_gens));
| ^~~~~~~~~~~~~~~~~~~
fs/bcachefs/util.h:223:54: note: expanded from macro 'prt_printf'
223 | #define prt_printf(_out, ...) bch2_prt_printf(_out, __VA_ARGS__)
| ^~~~~~~~~~~
On 64-bit architectures, size_t is 'unsigned long', so there is no
warning when using %lu but on 32-bit architectures, size_t is 'unsigned
int'. Use '%zu', the format specifier for 'size_t', to eliminate the
warning.
