bpf, powerpc: Fix misuse of fallthrough in bpf_jit_comp()

The user defined label following "fallthrough" is not considered by GCC and causes build failure. kernel-source/include/linux/compiler_attributes.h:208:41: error: attribute 'fallthrough' not preceding a case label or default label [-Werror] 208 define fallthrough _attribute((fallthrough_)) ^~~~~~~~~~~~~ Fixes: df561f6 ("treewide: Use fallthrough pseudo-keyword") Signed-off-by: He Zhe <zhe.he@windriver.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Cc: Gustavo A.
