x86/bugs: Remove x86_spec_ctrl_set()
commit 4b59bdb569453a60b752b274ca61f009e37f4dae upstream
x86_spec_ctrl_set() is only used in bugs.c and the extra mask checks there
provide no real value as both call sites can just write x86_spec_ctrl_base
to MSR_SPEC_CTRL. x86_spec_ctrl_base is valid and does not need any extra
masking or checking.
