crypto: x86/sm4 - Fix invalid section entry size
This fixes the following warning:
vmlinux.o: warning: objtool: elf_update: invalid section entry size
The size of the rodata section is 164 bytes, directly using the
entry_size of 164 bytes will cause errors in some versions of the
gcc compiler, while using 16 bytes directly will cause errors in
the clang compiler. This patch correct it by filling the size of
rodata to a 16-byte boundary.

Fixes: 5b2efa2bb865 ("crypto: x86/sm4 - add AES-NI/AVX2/x86_64 implementation")
