Modified Files:
        src/sys/dev/usb: ehci.c

Log Message:
in alloc_sqtd_chain(), deal with the case where a data packet ends
exactly at a page boundary, and the FORCE_SHORT_XFER was set by the
client (which causes that an empty descriptor is needed to terminate
the transfer), from Gordon McNutt per PR kern/44883
(fixed a bit differently than the proposed patch for aesthetical
reasons -- avoids the page pointer to come into unexpexted area earlier)
