RDMA/bnxt_re: Add sanity checks on rdev validity

Browse source

[ Upstream commit f0df225d12 ]

There is a possibility that ulp_irq_stop and ulp_irq_start
callbacks will be called when the device is in detached state.
This can cause a crash due to NULL pointer dereference as
the rdev is already freed.
