[PATCH] KVM: arm64: Drop 'const' from argument of vq_present()

[Viresh Kumar]

We currently get following compilation warning:

arch/arm64/kvm/guest.c: In function 'set_sve_vls':
arch/arm64/kvm/guest.c:262:18: warning: passing argument 1 of 'vq_present' from incompatible pointer type
arch/arm64/kvm/guest.c:212:13: note: expected 'const u64 (* const)[8]' but argument is of type 'u64 (*)[8]'

The argument can't be const, as it is copied at runtime using
copy_from_user(). Drop const from the prototype of vq_present().

Fixes: 9033bba4b535 ("KVM: arm64/sve: Add pseudo-register for the guest's vector lengths")
