qpnp-qnovo: fix ptrain done handler 



Currently the handler skips calling the update function
but uses the final result from the votable not_ok_to_qnovo_votable.
Fix it by calling the update function so it gets a chance to vote on
not_ok_to_qnovo_votable.

Moreover do not return early from ptrain_done handler without setting
QNI_PT_VOTER's vote on pt_dis_votable. This is a self clearing bit and
unless QNI_PT_VOTER's bit is removed, the next restart may not trickle
down to hw.
