[IRDA]: Possible cleanups.

This patch contains the following possible cleanups:

- make the following needlessly global function static:
  - irnet/irnet_ppp.c: irnet_init

- remove the following unneeded EXPORT_SYMBOL's:
  - irlmp.c: sysctl_discovery_timeout
  - irlmp.c: irlmp_reasons
  - irlmp.c: irlmp_dup
  - irqueue.c: hashbin_find_next
