qcacld-3.0: Fix block comments in wlan_hdd_p2p.h

A checkpatch run on the HDD component has produced numerous
warnings about improper block comments:
WARNING: Block comments use * on subsequent lines
WARNING: Block comments should align the * on each line
WARNING: Block comments use a trailing */ on a separate line

Fix all such warnings in wlan_hdd_p2p.h.
