x86/fpu: Rename fpu_reset_fpregs() to fpu_reset_fpstate_regs()
The original function name came from an overly compressed form of
'fpstate_regs' by commit:
e61d6310a0f8 ("x86/fpu: Reset permission and fpstate on exec()")
However, the term 'fpregs' typically refers to physical FPU registers. In
contrast, this function copies the init values to fpu->fpstate->regs, not
hardware registers.
Rename the function to better reflect what it actually does.
No functional change.
