be2iscsi: Fix to use atomic bit operations for tag_state

beiscsi_mccq_compl sets MCC_TAG_STATE_TIMEOUT before setting up
tag_mem_state. be_mcc_compl_process_isr checks for MCC_TAG_STATE_TIMEOUT
first then accesses tag_mem_state which might be still getting populated
in the process context.

Fix: Set MCC_TAG_STATE_TIMEOUT after tag_mem_state is populated.
Removed MCC_TAG_STATE_COMPLETED. When posted its in running state and
the running state is cleared in be_mcc_compl_process_isr.  be_mcc_notify
now takes tag argument to set it to running state.  Use bit operations
for tag_state. Use barriers before setting the state.
