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: df561f6688fe ("treewide: Use fallthrough pseudo-keyword")
