mshv: Fix compiler warning about cast converting incompatible function type

Browse source

In mshv_vtl_sint_ioctl_pause_msg_stream(), the reference to function
mshv_vtl_synic_mask_vmbus_sint() is cast to type smp_call_func_t. The
cast generates a compiler warning because the function signature of
mshv_vtl_synic_mask_vmbus_sint() doesn't match smp_call_func_t.

There's no actual bug here because the mis-matched function signatures
are compatible at runtime. Nonetheless, eliminate the compiler warning
by changing the function signature of mshv_vtl_synic_mask_vmbus_sint()
to match what on_each_cpu() expects. Remove the cast because it is then
no longer necessary.

No functional change.
