Kuniyuki Iwashima 2db60bb564 bpf: Fix SO_RCVBUF/SO_SNDBUF handling in _bpf_setsockopt().
[ Upstream commit 04c350b1ae ]

The commit 4057765f2d ("sock: consistent handling of extreme
SO_SNDBUF/SO_RCVBUF values") added a change to prevent underflow
in setsockopt() around SO_SNDBUF/SO_RCVBUF.

This patch adds the same change to _bpf_setsockopt().

Fixes: 4057765f2d ("sock: consistent handling of extreme SO_SNDBUF/SO_RCVBUF values")
