ANDROID: vendor hooks: use DECLARE_RESTRICTED_HOOK for android_rvh

Browse Source 
The callback function bound to the android_rvh declared by
DECLARE_HOOK() cannot be called in cpu offline or non-atomic
context, otherwise it will report "BUG: scheduling while
atomic" problem, so use DECLARE_RESTRICTED_HOOK() instead.
