msm: ipa: Fix to accessing ipa_q6_clnt handle



There is a possibility that ipa_q6_clnt handle is used
after it is freed espcially in scenarios where the handle
is freed on service exited notification. Make a change to
not clean up the handle when service is exited instead
do it as part of BEFORE_POWERUP processing only.
