octeontx2-pf: Fix RSS indirection table size

The conversion to the dedicated RSS context operations replaced the
pointer to struct otx2_rss_ctx with an inline u32 ind_tbl[] array.
However, otx2_rss_init() still uses sizeof(*rss->ind_tbl) to set rss_size.
This now yields the size of one u32 (4), rather than the 256 entries in
the indirection table.

The RSS initialization and hardware programming loops use rss_size,
so only four entries are initialized and programmed despite the NIX LF
being allocated a 256-entry table. On an OCTEON CN102 with eight RX
queues, the table contained 0, 1, 2, 3 followed by zeros. Traffic was
concentrated on queue 0 and ethtool -X equal 8 did not correct the table.

Use ARRAY_SIZE() to count the indirection table entries. On the same
hardware, this restores the full table repeating queue numbers 0 through
7, and bidirectional multi-flow traffic increments multiple RX queues.

Runtime testing on an Asterfusion ET2500 (OCTEON CN102 A0).
