Richard Henderson 497273cecf accel/tcg: Use TLB_FORCE_SLOW not TLB_MMIO for user-only plugins 
In 6d03226b42 we set TLB_MMIO to a non-zero value for user-only
so that we could return a non-zero value from probe_* functions
so that we could force callers like Arm SVE vector moves to use
the slow path rather than direct access.  All for the sake of
exposing these accesses to plugins.

Back then, TLB_FORCE_SLOW did not exist, so TLB_MMIO seemed like
a reasonable solution.  However, user-only doesn't really have
MMIO and this has knock-on effects, like forcing Arm SVE first-fault
vector loads to stop.  Better to use TLB_FORCE_SLOW as a more exact
trigger for plugins.
