btrfs: use the correct const function attribute for btrfs_get_num_csums
The build robot reports compiler: h8300-linux-gcc (GCC) 9.3.0 In file included from fs/btrfs/tests/extent-map-tests.c:8: >> fs/btrfs/tests/../ctree.h:2166:8: warning: type qualifiers ignored on function return type [-Wignored-qualifiers] 2166 | size_t __const btrfs_get_num_csums(void); | ^~~~~~~ The function attribute for const does not follow the expected scheme and in this case is confused with a const type qualifier.
