Subject: [PATCH v1 14/14] tee: shm: inline tee_shm_get_id()

From: Volodymyr Babchuk <vlad.babchuk@...il.com>

Now, when struct tee_shm is defined in public header,
we can inline small getter functions like this one.

 * Previously this patch moved tee_shm_is_registered() also,
   but now it is declared as inline in the same patch that
   adds it. So now this change moves only tee_shm_get_id().
   Commit message was changed accordingly.
