vhost/scsi: Add pre-allocation for tv_cmd SGL + upages memory
This patch adds support for pre-allocation of per tv_cmd descriptor scatterlist + user-space page pointer memory using se_sess->sess_cmd_map within tcm_vhost_make_nexus() code. This includes sanity checks within vhost_scsi_map_to_sgl() to reject I/O that exceeds these initial hardcoded values, and the necessary cleanup in tcm_vhost_make_nexus() failure path + tcm_vhost_drop_nexus(). v3 changes: - Rebase to v3.11-rc5 code Cc: Michael S.
