meta-flow: Avoid null pointer dereference in mf_format_frag_string().

The 'maskp' parameter to this function can be NULL, but the function
always dereferenced it.  This commit fixes the problem.

This commit also fixes the order in which the value and mask were adjusted
to correctly discard 1-bits outside of FLOW_NW_FRAG_MASK.

Found by Coverity.
