RDMA/bnxt_re: Pass the context for ulp_irq_stop
ulp_irq_stop() can be invoked from a context where FW is healthy or
when FW is in a reset state. In the latter case, ULP must stop all
interactions with HW/FW and also with application and stack. Added a
new parameter to the ulp_irq_stop() function to achieve that.
