qed: Avoid implicit enum conversion in qed_roce_mode_to_flavor

Browse Source 
Clang warns when one enumerated type is implicitly converted to another.

drivers/net/ethernet/qlogic/qed/qed_roce.c:153:12: warning: implicit
conversion from enumeration type 'enum roce_mode' to different
enumeration type 'enum roce_flavor' [-Wenum-conversion]
                flavor = ROCE_V2_IPV6;
                       ~ ^~~~~~~~~~~~

conversion from enumeration type 'enum roce_mode' to different
enumeration type 'enum roce_flavor' [-Wenum-conversion]

Use the appropriate values from the expected type, roce_flavor:

ROCE_V2_IPV6 = RROCE_IPV6 = 2
MAX_ROCE_MODE = MAX_ROCE_FLAVOR = 3

While we're add it, ditch the local variable flavor, we can just return
the value directly from the switch statement.
