PM: Stop Power Manager Timer if in sniff mode - do not merge 

Power manager timer is started when ACL link is in active mode
depending on profile connected. This timer was never stopped
when link was put in sniff mode by remote device preventing
system from going to sleep since timer is still active resulting
in extra power consumption.
