erofs: fix error return code in erofs_read_superblock()
commit0508c1ad0f
upstream. 'ret' will be overwritten to 0 if erofs_sb_has_sb_chksum() return true, thus 0 will return in some error handling cases. Fix to return negative error code -EINVAL instead of 0. Link: https://lore.kernel.org/r/20210519141657.3062715-1-weiyongjun1@huawei.com Fixes:b858a4844c
