x86/asm/crypto: Move .Lbswap_mask data to .rodata section
stacktool reports the following warning:
stacktool: arch/x86/crypto/aesni-intel_asm.o: _aesni_inc_init(): can't find starting instruction
stacktool gets confused when it tries to disassemble the following data
in the .text section:
.Lbswap_mask:
.byte 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
Move it to .rodata which is a more appropriate section for read-only
data.
