octeontx2-pf: Wait till detach_resources msg is complete

Browse Source 
[ Upstream commit cbf2f24939a5dafce6de4dd4422e543ce8f610cf ]

During VF driver remove, a message is sent to detach VF
resources to PF but VF is not waiting until message is
complete. Also mailbox interrupts need to be turned off
after the detach resource message is complete. This patch
fixes that problem.
