iw_cxgb4: Use proper enumerated type in c4iw_bar2_addrs

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

drivers/infiniband/hw/cxgb4/qp.c:287:8: warning: implicit conversion
from enumeration type 'enum t4_bar2_qtype' to different enumeration type
'enum cxgb4_bar2_qtype' [-Wenum-conversion]
                                                 T4_BAR2_QTYPE_EGRESS,
                                                 ^~~~~~~~~~~~~~~~~~~~

c4iw_bar2_addrs expects a value from enum cxgb4_bar2_qtype so use the
corresponding values from that type so Clang is satisfied without changing
the meaning of the code.

T4_BAR2_QTYPE_EGRESS = CXGB4_BAR2_QTYPE_EGRESS = 0
T4_BAR2_QTYPE_INGRESS = CXGB4_BAR2_QTYPE_INGRESS = 1
