remote: make match_refs() not short-circuit

match_refs() returns non-zero if there is an error in
match_explicit_refs(), without handling any remaining pattern ref specs.

Its existing callers exit upon receiving non-zero, so a partial result
is of no consequence to them; however a new caller, builtin-remote, is
interested in the complete result even if there are errors in
match_explicit_refs().
