xkb: after changing the keymap, force an indicator update
When NumLock is on and a new keymap is applied, the next modifier state
change will turn off that LED (but leave the state enabled). The cause
for this is a bit convoluted:
* the SLI explicitState is copied from the current state in
ProcXkbGetKbdByName. Thus, if NumLock is on, that state is 0x2.
* on the next modifier key press (e.g. Shift), XkbApplyState() calls into
XkbUpdateIndicators() -> XkbUpdateLedAutoState() to update SLIs (if any)
for the currently changed modifier. But it does so with a mask only for
the changed modifier (i.e. for Shift).
* XkbUpdateLedAutoState() calculates the state based on this mask and
ends up with 0 because we don't have a Shift LED and we masked out the
others.
* XkbUpdateLedAutoState() compares that state with the previous state
(which is still 0x2) and then proceeds to turn the LED off
This doesn't happen in the normal case because either the mask
encompasses all modifiers or the state matches of the masked-out
modifiers matches the old state.
Avoid this issue by forcing an SLI update after changing the keymap.
This updates the sli->effectiveState and thus restores everything to
happy working order.
