USB: garmin_gps: fix memory leak on disconnect
commit 618aa1068df29c37a58045fe940f9106664153fd upstream. Remove bogus disconnect test introduced by 95bef012e ("USB: more serial drivers writing after disconnect") which prevented queued data from being freed on disconnect. The possible IO it was supposed to prevent is long gone.
