ext4: fix miss unlock 'sb->s_umount' in extents_kunit_init()
There's warning as follows when do ext4 kunit test:
WARNING: kunit_try_catch/15923 still has locks held!
7.0.0-rc3-next-20260309-00028-g73f965a1bbb1-dirty #281 Tainted: G E N

As sget() will return 'sb' which holds 's->s_umount' lock. However,
"extents-test" miss unlock this lock.
So unlock 's->s_umount' in the end of extents_kunit_init().
Fixes: cb1e0c1d1fad ("ext4: kunit tests for extent splitting and conversion")
