ext4: add extra checks to ext4_xattr_block_get()
...
commit 54dd0e0a1b255f115f8647fc6fb93273251b01b9 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.
