The __is_valid_access() test for cb[] from 62c7989b ("bpf: allow b/h/w/dw access for bpf's cb in ctx") was done unnecessarily complex, we can just simplify it the same way as recent fix from 2d071c64 ("bpf, trace: make ctx access checks more robust") did. Overflow can never happen as size is 1/2/4/8 depending on access. Signed-off-by:
