net/macb: fix misplaced call of free_netdev() in macb_remove()

Browse Source 
fix a bug introduced by the multiqueue support patch:
"net/macb: add TX multiqueue support for gem"

the "bp" pointer to the netdev private data was dereferenced and used after the
associated memory had been freed by calling free_netdev().
