[PATCH rdma-next 1/2] RDMA/ionic: Fix build failure on SPARC due to xchg() operand size

[Abhijit Gangurde]

xchg() is used to safely handle the event queue arming.
However SPARC xchg operates only 4B of variable.
Change variable type from bool to int.

Unverified Error/Warning (likely false positive, kindly check if interested):

    ERROR: modpost: "__xchg_called_with_bad_pointer" [drivers/infiniband/hw/ionic/ionic_rdma.ko] undefined!
