Add missing checks to zpl_xattr_* functions
Linux specific zpl_* entry points, such as xattrs, must include
the same unmounted and sa handle checks as the common zfs_ entry
points. The additional ZPL_* wrappers are identical to their
ZFS_ counterparts except the errno is negated since they are
expected to be used at the zpl_ layer.
