isofs: replace ll_rw_block()

mainline inclusion
from mainline-v6.1-rc1
commit 0ed48061
category: bugfix
bugzilla: 187878,https://gitee.com/openeuler/kernel/issues/I5QJH9
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.1-rc2&id=0ed48061887f603b33b7dcb9075cbfaaa8d02723

--------------------------------

ll_rw_block() is not safe for the sync read path because it cannot
guarantee that submitting read IO if the buffer has been locked. We
could get false positive EIO return from zisofs_uncompress_block() if
he buffer has been locked by others. So stop using ll_rw_block(),
switch to sync helper instead.
