Subject: net/mlx5: DR, Add check for flex parser ID value
Patch-mainline: v5.17-rc1
Git-commit: 89cdba3224f07703e2272212db131cabe152979e
References: jsc#PED-1549
Allow only legal values for flex parser ID - values from 0 to 7.
For other values skip the parser, and as a result the matcher creation
will fail for using invalid flex parser ID.
