[PATCH] net: octeontx2: fix building without DEBUGFS

From: Arnd Bergmann <arnd@arndb.de>

This error came up on my randconfig tests this week:

drivers/net/ethernet/marvell/octeontx2/af/cn20k/debugfs.c: In function 'npc_cn20k_debugfs_init':
drivers/net/ethernet/marvell/octeontx2/af/cn20k/debugfs.c:392:55: error: 'struct rvu' has no member named 'rvu_dbg'; did you mean 'rvu_dl'?
  392 |         debugfs_create_file("mcam_layout", 0444, rvu->rvu_dbg.npc,

The problem here is that the rvu_dbg member is hidden in an #ifdef
block, but the reference to it is not.

Remove the #ifdef and waste the 8 bytes in the structure in this
config. Note that the debugfs_create_file() call end up ignoring
the arguments, so the actual debugfs implementation is still
ignored here.

Fixes: 45229e9a9ab5 ("octeontx2-af: Extend debugfs support for cn20k NIX")

I cannot tell why this showed up now and not earlier, so maybe the
'Fixes' line is misplaced. In randconfig builds, debugfs is almost
always selected by something else, while the octeontx2 driver is
usually disabled, so it does make some sense that this config
would be rate.
