Building the fat kunit tests on with -fsanitize=alignment reveals some
rather excessive stack usage:
fs/fat/fat_test.c: In function 'fat_clus_to_blknr_test':
fs/fat/fat_test.c:33:1: error: the frame size of 4736 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
33 | }
| ^
fs/fat/fat_test.c: In function 'fat_get_blknr_offset_test':
fs/fat/fat_test.c:52:1: error: the frame size of 4800 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
The problem is clearly related to the on-stack copy of a local
msdos_sb_info structure. Avoid this by making that copy 'static const'
and changing the called functions to accept a constant input.
