[PATCH 3/3] builtin/apply: simplify gitdiff_{old,new}name()

[Christian Couder <christian.couder@gmail.com>]

After the previous simplifications, it is easy to see that
there is no need to free the original string passed to
gitdiff_verify_name(), because this string can be changed
only when it is NULL.
