Shung-Hsi Yu 1ae497c78f bpf: use type_may_be_null() helper for nullable-param check 
Commit 980ca8ceea ("bpf: check bpf_dummy_struct_ops program params for
test runs") does bitwise AND between reg_type and PTR_MAYBE_NULL, which
is correct, but due to type difference the compiler complains:

  net/bpf/bpf_dummy_struct_ops.c:118:31: warning: bitwise operation between different enumeration types ('const enum bpf_reg_type' and 'enum bpf_type_flag') [-Wenum-enum-conversion]
    118 |                 if (info && (info->reg_type & PTR_MAYBE_NULL))
        |                              ~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~

Workaround the warning by moving the type_may_be_null() helper from
verifier.c into bpf_verifier.h, and reuse it here to check whether param
is nullable.

Fixes: 980ca8ceea ("bpf: check bpf_dummy_struct_ops program params for test runs")
