Several recent regressions and some bug fixes
 
 - Typo corrupting the max_recv_sge for cxgb4
 
 - Regression from re-using kernel enums as a HW AbI in vmw_pvrdma
 
 - Sleeping inside a spinlock in hns
 
 - Revert the attempt to fix devlink deadlocks as the fix is more buggy
 
 - Typo in sysfs_emit_at conversions
 
 - Revert the removal of VLAN support in rxe
