Yafang Shao a8795ba899 bpf: sock recvbuff must be limited by rmem_max in bpf_setsockopt()
[ Upstream commit c9e4576743 ]

When sock recvbuff is set by bpf_setsockopt(), the value must by
limited by rmem_max. It is the same with sendbuff.

Fixes: 8c4b4c7e9f ("bpf: Add setsockopt helper function to bpf")
