Hou Tao 05c1558bfc libbpf: Check the validity of size in user_ring_buffer__reserve() 
The top two bits of size are used as busy and discard flags, so reject
the reservation that has any of these special bits in the size. With the
addition of validity check, these is also no need to check whether or
not total_size is overflowed.
