anv/sparse: don't issue a single bind operation per vm_bind ioctl

Browse source 
The xe.ko driver finally fixed bug 746, which means we can finally
pass multiple bind operations in a single ioctl. There's a dEQP test
that issues 960 bind operations in a single call, so our gains here
have potential, although most real-world apps are not even remotely
close to this.
