Major rework of CM connection setup/teardown. We had a number of issues
with MPI applications not starting/terminating properly over time.
With these changes we were able to run longer on larger clusters.
* Remove memory allocation from nes_connect() and nes_cm_connect().
* Fix mini_cm_dec_refcnt_listen() when destroying listener.
* Remove unnecessary code from schedule_nes_timer() and nes_cm_timer_tick().
* Functionalize mini_cm_recv_pkt() and process_packet().
* Clean up cm_node->ref_count usage.
* Reuse skbs if available.

Every caller of nes_post_cqp_request() passed it NES_CQP_REQUEST_RING_DOORBELL,
so just remove that parameter and always ring the doorbell.

Fix some bugs with the max_aggr module parameter added with LRO support:
- The module parameter value ignored and not actually used to set
lro_mgr.max_aggr.
- MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
end up describing the actual module parameter.
- The nes_lro_max_aggr variable was declared as unsigned, but the
module_param line said "int" instead of "uint" for the type.
- The default value for the parameter was stuck in the permissions
field of module_param, which led to nonsensical permissions for the
file under /sys/module/iw_nes/param.
- The parameter was used in only one file but defined in another, which
led to the variable being global for no good reason. Move everything
related to the parameter to the file nes_hw.c where it is actually
used.

before they are used in the source.

Move the free_irq() call in nes_remove() to before the tasklet_kill();
otherwise there is a window after tasklet_kill() where a new interrupt
can be handled and reschedule the tasklet, leading to a use-after-free
crash.
