KVM: x86: hyper-v: Fix the maximum number of sparse banks for XMM fast TLB flush hypercalls
When TLB flush hypercalls (HVCALL_FLUSH_VIRTUAL_ADDRESS_{LIST,SPACE}_EX are
issued in 'XMM fast' mode, the maximum number of allowed sparse_banks is
not 'HV_HYPERCALL_MAX_XMM_REGISTERS - 1' (5) but twice as many (10) as each
XMM register is 128 bit long and can hold two 64 bit long banks.
Cc: stable@vger.kernel.org # 5.14.x
