[Openib-windows] Create AV with GRH from user space

[Yossi Leybovich]

Fab 

Attached patch that cached the hca_attr after the first query.
We still need to figure if the cache of CA attr in UL is good idea , but
till then this patch unable use to send GRH from UL.

(I also add the case to the alts test so we can cover this flow)
