nfp: flower: get flows by host context
Each flow is given a context ID that the fw uses (along with its cookie)
to identity the flow. The flows stats are updated by the fw via this ID
which is a reference to a pre-allocated array entry.
In preparation for flow merge code, enable the nfp_fl_payload structure to
be accessed via this stats context ID. Rather than increasing the memory
requirements of the pre-allocated array, add a new rhashtable to associate
each active stats context ID with its rule payload.
While adding new code to the compile metadata functions, slightly
restructure the existing function to allow for cleaner, easier to read
error handling.
