USB: Speedtouch: add pre_reset and post_reset routines
This patch (as1150) fixes a problem in the speedtch driver. When it resets the modem during probe it will be unbound from the other interfaces it has claimed, because it doesn't define a pre_reset and a post_reset method. The patch defines "do-nothing" methods. This fixes Bugzilla #11767.
