LinuxKPI: Allow kmalloc to be called when FPU protection is enabled
Amdgpu driver does a lot of memory allocations in FPU-protected sections
of code for certain display cores, e.g. for DCN30. This does not work
on FreeBSD as its malloc function can not be run within a critical
section. Check this condition and temporally exit from FPU-protected
context to workaround issue and reduce source code patching.
