Subject: [PATCH][next] netxen_nic: remove redundant assignment to variable capability

The variable capability is being assigned a value that is never
read and is being re-assigned later. The assignment is redundant and
can be removed. Also remove empty line before assignment to capability.

Cleans up clang scan build warning:
drivers/net/ethernet/qlogic/netxen/netxen_nic_init.c:1189:2: warning:
Value stored to 'capability' is never read [deadcode.DeadStores]
