[PATCH] fetch: do not redundantly calculate tag refmap

[Jonathan Tan <jonathantanmy@google.com>]

builtin/fetch.c redundantly calculates refmaps for tags twice. Remove
the first calculation.

This is only a code simplification and slight performance improvement -
the result is unchanged, as the redundant refmaps are subsequently
removed by the invocation to "ref_remove_duplicates" anyway.

This was introduced in commit c5a84e9 ("fetch --tags: fetch tags *in
addition to* other stuff", 2013-10-29) when modifying the effect of the
--tags parameter to "git fetch". The refmap-for-tag calculation was
copied instead of moved.
