x86/bugs: Fix return type of spectre_bhi_state()
commit 04f4230e2f86a4e961ea5466eda3db8c1762004d upstream.
The definition of spectre_bhi_state() incorrectly returns a const char
* const. This causes the a compiler warning when building with W=1:
warning: type qualifiers ignored on function return type [-Wignored-qualifiers]
2812 | static const char * const spectre_bhi_state(void)
Remove the const qualifier from the pointer.
Fixes: ec9404e40e8f ("x86/bhi: Add BHI mitigation knob")
