Fix CONFIG_X86_DEBUG_FPU build failure
When CONFIG_X86_DEBUG_FPU is defined the alternatives_patched symbol
is pulled in as a dependency which results in a build failure. To
prevent this undefine CONFIG_X86_DEBUG_FPU to disable the WARN_ON_FPU()
macro and rely on WARN_ON_ONCE debugging checks which were previously
added.
