gve: unify driver name usage

Current codebase contained the usage of two different names for this
driver (i.e., `gvnic` and `gve`), which is quite unfriendly for users
to use, especially when trying to bind or unbind the driver manually.
The corresponding kernel module is registered with the name of `gve`.
It's more reasonable to align the name of the driver with the module.
