md/raid1: fix error: ISO C90 forbids mixed declarations
There is a compile error when this commit is added: md: raid1: fix potential OOB in raid1_remove_disk() drivers/md/raid1.c: In function 'raid1_remove_disk': drivers/md/raid1.c:1844:9: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement] 1844 |         struct raid1_info *p = conf->mirrors + number;     |         ^~~~~~ That's because the new code was inserted before the struct. The change is move the struct command above this commit.
