IB/ehca: handle negative return value from ibmebus_request_irq() properly

ehca_create_eq() was assigning a signed return value to an unsiged
local variable and then checking if the variable was < 0, which meant
that errors were always ignored.  Fix this by using one variable for
signed integer return values and another for u64 hcall return values.
