[PATCH v3] x86: fix the error of using "const" in gen-insn-attr-x86.awk

x86: fix the error of using "const" in gen-insn-attr-x86.awk

The original version code causes following sparse warnings:
arch/x86/lib/inat-tables.c:1080:25: warning: duplicate const
arch/x86/lib/inat-tables.c:1095:25: warning: duplicate const
arch/x86/lib/inat-tables.c:1118:25: warning: duplicate const

for the variables inat_escape_tables, inat_group_tables, and inat_avx_tables
in the code generated by gen-insn-attr-x86.awk.

The author Masami Hiramutsu says here is to make both the value pointed by the
pointers and the pointers itself read-only, so we move the "const" to be after
the "*".
