[PATCH] ath6kl: Use cc-disable-warning to disable -Wdangling-pointer

Clang does not support this option so the build fails:

error: unknown warning option '-Wno-dangling-pointer' [-Werror,-Wunknown-warning-option]

Use cc-disable-warning so that the option is only added when it is
supported.

Fixes: bd1d129daa3e ("wifi: ath6k: silence false positive -Wno-dangling-pointer warning on GCC 12")
