vmxnet3: custom dump and debug cli fix

Add missing custom dump for vmxnet3_create, vmxnet3_delete, and
vmxnet3_dump.

Fix vmxnet3_create debug cli which may not parse all parameters
correctly due to passing address of u16 to unformat(). The fix is
to use a u32 local variable to receive the correct value from
unformat().

Type: fix
