Synchronous calls for meter ASO try to pull pending completions
from CQ, submit WR and return to caller. That avoids delays between
WR post and HW response.
If the template API was activated, PMD will use control queue for
sync operations.
PMD has different formats for the `user_data` context in sync and
async meter ASO calls.
PMD port destruction procedure submits async operations to the port
control queue and polls the queue CQs to clean HW responses.
Port destruction can pull a meter ASO completion from control CQ.
Such completion has sync format, but was processed by async handler.
The patch implements sync meter ASO interface with async calls
in the template API environment.
Fixes: 48fbb0e93d06 ("net/mlx5: support flow meter mark indirect action with HWS")

MLX5 PMD driver supports 2 types of indirect actions:
legacy INDIRECT and INDIRECT_LIST.
PMD has different handlers for each of indirection actions types.
Therefore PMD marks async `job::indirect_type` with relevant value.
PMD set the type only during indirect action creation.
Legacy INDIRECT query could have get a job object used previously by
INDIRECT_LIST action. In that case such job object was handled as
INDIRECT_LIST because the `job::indirect_type` was not re-assigned.
The patch sets `job::indirect_type` during the job initialization
according to operation type.
Fixes: 59155721936e ("net/mlx5: fix indirect flow completion processing")
