Log Message:
Pull up following revision(s) (requested by riastradh in ticket #1493):
sys/dev/usb/ucom.c: revision 1.129
ucom(4): Fix earlier mistake causing pipes not to be closed.
In revision 1.123, mrg@ changed what he thought was a double-close,
but was actually abort&close (as is appropriate) to just abort (which
is not enough -- leaks the pipe). This restores the abort&close.
The original `bug' was found by code inspection, whereas this bug was
found by asserting in usb_subr.c that no pipes are open on device
disconnection after detach; the asserts actually triggered with
several ucom(4) devices, and no longer trigger with this change.
