BACKPORT [UPSTREAM] ext4: convert to mbcache2

(Cherry-pick from commit 82939d7999dfc1f1998c4b1c12e2f19edbdff272)

The conversion is generally straightforward. The only tricky part is
that xattr block corresponding to found mbcache entry can get freed
before we get buffer lock for that block. So we have to check whether
the entry is still valid after getting buffer lock.
