x86/fpu: Remove redundant XCOMP_BV initialization

Browse source

fpu_copy_uabi_to_guest_fpstate() initializes the XCOMP_BV field in the
XSAVE header. That's a leftover from the old KVM FPU buffer handling code.

Since

  d69c1382e1 ("x86/kvm: Convert FPU handling to a single swap buffer")

KVM uses the FPU core allocation code, which initializes the XCOMP_BV
field already.
