Subject: [PATCH net-next] bonding: Remove extraneous parentheses in bond_setup

Clang warns:

drivers/net/bonding/bond_main.c:4657:23: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        if ((BOND_MODE(bond) == BOND_MODE_ACTIVEBACKUP))
             ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

drivers/net/bonding/bond_main.c:4681:23: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        if ((BOND_MODE(bond) == BOND_MODE_ACTIVEBACKUP))
             ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

This warning occurs when a comparision has two sets of parentheses,
which is usually the convention for doing an assignment within an
if statement. Since equality comparisons do not need a second set of
parentheses, remove them to fix the warning.
