    bpf: Fix warning for cast from restricted gfp_t in verifier

    This fixes the sparse warning reported by the kernel test robot:

    kernel/bpf/verifier.c:13499:47: sparse: warning: cast from restricted gfp_t
    kernel/bpf/verifier.c:13501:47: sparse: warning: cast from restricted gfp_t

    This fix can be verified locally by running:
    1) wget
    https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross


    -O make.cross

    2) chmod +x ~/bin/make.cross

    3) COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-11.2.0 ./make.cross
    C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

    Fixes: b00fa38a ("bpf: Enable non-atomic allocations in local storage")
