xfs: move the xfs_attr_sf_lookup tracepoint

Source kernel commit: 14f2e4ab5d0310c2bb231941d9884fa5bae47fab

trace_xfs_attr_sf_lookup is currently only called by
xfs_attr_shortform_lookup, which despit it's name is a simple helper for
xfs_attr_shortform_addname, which has it's own tracing.  Move the
callsite to xfs_attr_shortform_getvalue, which is the closest thing to
a high level lookup we have for the Linux xattr API.
