octeontx2-pf: Use default max_active works instead of one
[ Upstream commit 7558ce0d974ced1dc07edc1197f750fe28c52e57 ]
Only one execution context for the workqueue used for PF and
VFs mailbox communication is incorrect since multiple works are
queued simultaneously by all the VFs and PF link UP messages.
Hence use default number of execution contexts by passing zero
as max_active to alloc_workqueue function. With this fix in place,
modify UP messages also to wait until completion.
