Remove old style mod inc/dec from this WAN driver.

Get rid of leftover MOD INC/DEC in this driver.  Ref counting now done
by network core.

Jeff, please apply to net-drivers-2.5-exp

skfp_probe used to be called from Space.c but isn't any more.
Therefore it no longer needs to be global.  All the calls to insert_device()
pass skfp_probe as a second arg, so just use it directly.

Jeff, this also is janitor type stuff, so just put it in net-2.5-exp

Get rid of warning now that module refcounting now done by network code not drivers.

Not tested on real hardware.
