Jitendra Bhivare 6ac999efee be2iscsi: Fix soft lockup in mgmt_get_all_if_id path using bmbx ... We are taking mbox_lock spinlock which disables pre-emption before we poll for mbox completion. Waiting there with spinlock held in excess of 20s will cause soft lockup. Actual fix is to change mbox_lock to mutex. The changes are done in phases. This is the first part. 1. Changed mgmt_get_all_if_id to use MCC where after posting lock is released. 2. Changed be_mbox_db_ready_wait to busy wait for 12s max and removed wait_event_timeout. Added error handling code for IO reads. OPCODE_COMMON_QUERY_FIRMWARE_CONFIG mbox command takes 8s time when unreachable boot targets configured.
