net: 3com: 3c59x: remove set but not used variable 'mii_reg1'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/3com/3c59x.c: In function ‘vortex_up’:
drivers/net/ethernet/3com/3c59x.c:1551:9: warning: variable
‘mii_reg1’ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
