Subject: [PATCH] powerpc: net: bpf_jit_comp: Fix misuse of fallthrough

From: He Zhe <zhe.he@...driver.com>

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_))
                          ^~~~~~~~~~~~~
