x86/speculation: Use DECLARE_PER_CPU for x86_spec_ctrl_current
Clang warns:
arch/x86/kernel/cpu/bugs.c:58:21: error: section attribute is specified on redeclared variable [-Werror,-Wsection]
DEFINE_PER_CPU(u64, x86_spec_ctrl_current);
^
arch/x86/include/asm/nospec-branch.h:283:12: note: previous declaration is here
extern u64 x86_spec_ctrl_current;
^
1 error generated.
The declaration should be using DECLARE_PER_CPU instead so all
attributes stay in sync.
