util: remove unused VIR_DIR_CLOSE() macro
util: remove unused VIR_DIR_CLOSE() macro

Since every single use of DIR* was converted to use g_autoptr, this
function is not currently needed. Even if someone comes up with a
usage for a non-g_autoptr DIR* in the future, they can just use
virDirClose(), since there is no longer a semantic difference between
the two (VIR_DIR_CLOSE() previously had an extra & on the pointer so
that it could be transparently passed as a DIR** to virDirClose(), but
that was removed several commits back.)
