gdb/amd64: clean up unused variable
When building with clang 15, I got this,
CXX amd64-tdep.o
amd64-tdep.c:1410:13: error: variable 'insn' set but not used[-Werror,-Wunused-but-set-variable]
gdb_byte *insn = insn_details->raw_insn + modrm_offset;
^
1 error generated.
The function that uses this variable has been removed in this commit,
commit 870f88f7551b0f2d6aaaa36fb684b5ff8f468107

remove trivialy unused variables
Fix this by removing unused variable.
Tested by rebuilding on x86_64-linux with clang 15 and gcc 12.
