depca: fix warning in drivers/net/depca.c
fix warning:
drivers/net/depca.c: In function ‘depca_eisa_probe’:
drivers/net/depca.c:1564: warning: ‘mem_start’ may be used uninitialized in this function
this seems to be a real bug - depca_eisa_probe() does not check
for failure. Add it, symmetric to depca_isa_probe().
