Hongzhen Luo 679d8537e5 erofs: fix blksize < PAGE_SIZE for file-backed mounts 
[ Upstream commit bae0854160 ]

Adjust sb->s_blocksize{,_bits} directly for file-backed
mounts when the fs block size is smaller than PAGE_SIZE.

Previously, EROFS used sb_set_blocksize(), which caused
a panic if bdev-backed mounts is not used.

Fixes: fb17675026 ("erofs: add file-backed mount support")
