[PATCH rdma-rc v1] RDMA: Remove kernel private defines and reference to header from UAPI

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Remove references to private kernel header and defines from exported
ib_user_verb.h file.

The code snippet below is used to reproduce the issue:

 #include <stdio.h>
 #include <rdma/ib_user_verb.h>

 int main(void)
 {
	printf("IB_USER_VERBS_ABI_VERSION = %d\n", IB_USER_VERBS_ABI_VERSION);
	return 0;
 }

It fails during compilation phase with an error:
➜  /tmp gcc main.c
main.c:2:31: fatal error: rdma/ib_user_verb.h: No such file or directory
 #include <rdma/ib_user_verb.h>
                               ^
compilation terminated.
