vports are not grabbing module references but are releasing them. This causes the module reference count to decrement too many times and it wraps around past 0. The solution is to do a module_put() in fcoe_interface_release() so that the reference is only released when the fcoe_interface is released. There is a one-to-one relationship between the N_Port and the fcoe_interface, so the module reference will only be dropped when the N_Port is destroyed To create symetry in the code this patch moves the try_module_get() call into fcoe_interface_create(). This means that only the N_Port will grab a reference to the module when its corresponding fcoe_interface is created. This patch also makes it so that the fcoe_interface_create() routine encodes any error codes in the fcoe_interface pointer returned. This way its caller, fcoe_create(), can return an accurate error code.
