ehci: Replace bogus polling during suspend by taking bus lock.

The system is not at high IPL or limited to a single CPU at this
point; it is running essentially normally, just with some devices
suspended.  Other threads might be trying to touch EHCI registers,
which might have bad outcomes while we're suspending stuff.  Enabling
polling only makes sense if there is a single thread and single CPU
running, such as when we enter ddb on crash.
