The input and output values of *size parameter are equal on successful
return from ext4_xattr_inode_get(). On error return, the callers ignore
the output value so there is no need to update it.
Also check for NULL return from ext4_bread(). If the actual xattr inode
size happens to be smaller than the expected size, ext4_bread() may
return NULL which would indicate data corruption.
