[PATCH opensm] osm_drop_mgr.c: fix timeouts on Get Pkey from ext switch ports

[Hal Rosenstock <hal-LDSdmyG8hGV8YrgS2mwiifqBs+8SCbDb@public.gmane.org>]

From: Alex Netes <alexne-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

In case SM doesn't recieve PkeyTable GetResp from external switch ports,
it should clear the PkeyTable GetResp counter and set physp->need_update
= 2, in order to resend PkeyTable Get on the next sweep.
