crypto: x86/crc32c - fix building with clang ias
The clang integrated assembler complains about movzxw:
arch/x86/crypto/crc32c-pcl-intel-asm_64.S:173:2: error: invalid instruction mnemonic 'movzxw'
It seems that movzwq is the mnemonic that it expects instead,
and this is what objdump prints when disassembling the file.
Fixes: 6a8ce1ef3940 ("crypto: crc32c - Optimize CRC32C calculation with PCLMULQDQ instruction")
