nvmet-fcloop: refactor fcloop_nport_alloc and track lport

The checks for a valid input values are mixed with the logic to insert a
newly allocated nport. Refactor the function so that first the checks
are done.

This allows to untangle the setup steps into a more linear form which
reduces the complexity of the functions.

Also start tracking lport when a lport is assigned to a nport. This
ensures, that the lport is not going away as long it is still referenced
by a nport.
