Separate out _nvme_create_ctrl() as a simpler interface to
nvme_create_ctrl() which accepts a 'struct nvmf_context' as
argument.

Replace with nvme_ctrl_find() and make it static to avoid
function name clashes.

Re-implement __nvme_lookup_ctrl() as equivalent to nvme_lookup_ctrl()
but taking 'struct nvmf_context' as argument. Care needs to be taken
to handle the 'subsysnqn' entry in 'struct nvmf_context';
__nvme_ctrl_find() needs to be called with a 'NULL' subsysnqn as the
controller might be on any subsystem, and we need to set 'subsysnqn'
to the NQN of the subsystem the controller should be created in rather
than the subsysnqn from 'struct nvmf_context' (which might be empty).

Use 'struct nvmf_context' throughout the file to test the new
interface.

All functions have been converted to the new interface, so rename
__nvme_lookup_ctrl() to nvme_lookup_ctrl() and drop the wrapper.
