There is no need to check for recursive calls into fpudna().
Rename the associated ci_fpsaving field to 'unused'.
I'm not sure they could ever happen, you could get unwanted calls into
the fpu trap code while saving state when using INT13 - but these are
The return value from the i386 fpudna() was always 1 - possibly a historic
relic of the kernel fp emulation. Remove and don't check in trap.S.
The amd64 and i386 fpudna() code is now almost identical.
