kbuild: drop -Wno-unknown-warning-option from clang options
commit a0ae981eba8f07dbc74bce38fd3a462b69a5bc8e upstream. Since commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to cc-option to support clang"), cc-option and friends work nicely for clang. However, -Wno-unknown-warning-option makes clang happy with any unknown warning options even if -Werror is specified. Once -Wno-unknown-warning-option is added, any succeeding call of cc-disable-warning is evaluated positive, then unknown warning options are accepted. This should be dropped.
