IB/hfi1: Add explicit cast OPA_MTU_8192 to 'enum ib_mtu'
Clang warns:
drivers/infiniband/hw/hfi1/qp.c:198:9: warning: implicit conversion from enumeration type 'enum opa_mtu' to different enumeration type 'enum ib_mtu' [-Wenum-conversion]
mtu = OPA_MTU_8192;
~ ^~~~~~~~~~~~
enum opa_mtu extends enum ib_mtu. There are typically two ways to deal
with this:
* Remove the expected types and just use 'int' for all parameters and
types.
* Explicitly cast the enums between each other.
This driver chooses to do the later so do the same thing here.
Fixes: 6d72344cf6c4 ("IB/ipoib: Increase ipoib Datagram mode MTU's upper limit")
