bcachefs: Fix -Wformat in bch2_btree_key_cache_to_text()
When building bcachefs for 32-bit ARM, there is a compiler warning in
bch2_btree_key_cache_to_text() due to use of an incorrect format
specifier:
fs/bcachefs/btree_key_cache.c:1060:36: error: format specifies type 'size_t' (aka 'unsigned int') but the argument has type 'long' [-Werror,-Wformat]
1060 | prt_printf(out, "nr_freed:\t%zu", atomic_long_read(&c->nr_freed));
| ~~~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| %ld
fs/bcachefs/util.h:223:54: note: expanded from macro 'prt_printf'
223 | #define prt_printf(_out, ...) bch2_prt_printf(_out, __VA_ARGS__)
| ^~~~~~~~~~~
1 error generated.
On 64-bit architectures, size_t is 'unsigned long', so there is no
warning when using %zu but on 32-bit architectures, size_t is
'unsigned int'. Use '%lu' to match the other format specifiers used in
this function for printing values returned from atomic_long_read().
