ext4: move check under lock scope to close a race.
[ Upstream commit 280227a75b56ab5d35854f3a77ef74a7ad56a203 ]
fallocate() checks that the file is extent-based and returns
EOPNOTSUPP in case is not. Other tasks can convert from and to
indirect and extent so it's safe to check only after grabbing
the inode mutex.
