Subject: [PATCH] net/velocity: fix -Wunused-but-set-variable warnings

'curr_status' is declared as u32.
But this variable is not used after below statement.
   curr_status = vptr->mii_status & (~VELOCITY_LINK_FAIL);

This variable could be dropped to mute below warning message:

   drivers/net/ethernet/via/via-velocity.c:868:6:
   warning: variable ‘curr_status’ set but not used 
   [-Wunused-but-set-variable]
