ext4: remove duplicate definition of ext4_xattr_ibody_inline_set()

[ Upstream commit 310c097c2bdbea253d6ee4e064f3e65580ef93ac ]

ext4_xattr_ibody_inline_set() & ext4_xattr_ibody_set() have the exact
same definition.  Hence remove ext4_xattr_ibody_inline_set() and all
its call references. Convert the callers of it to call
ext4_xattr_ibody_set() instead.

[ Modified to preserve ext4_xattr_ibody_set() and remove
  ext4_xattr_ibody_inline_set() instead. -- TYT ]
