[SCSI] target: Remove procfs based target_core_mib.c code
This patch removes the legacy procfs based target_core_mib.c code, and moves the necessary scsi_index_tables functions and defines into target_core_transport.c and target_core_base.h code to allow existing fabric independent statistics to function. This includes the removal of a handful of 'atomic_t mib_ref_count' counters used in struct se_node_acl, se_session and se_hba to prevent removal while using seq_list procfs walking logic. [jejb: fix up compile failures] Signed-off-by: Nicholas A. Bellinger <nab@linux-iscsi.org> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
