Theodore Ts'o e7793f2a2a ext4: add extra checks to ext4_xattr_block_get() ...

commit 54dd0e0a1b upstream.

Add explicit checks in ext4_xattr_block_get() just in case the
e_value_offs and e_value_size fields in the the xattr block are
corrupted in memory after the buffer_verified bit is set on the xattr
block.
