Subject: [PATCH] iwlwifi: dbg_ini: don't skip a TX FIFO when dumping
Git-commit: efaaa97c0e7f14c48ee406a37ba25ff3915c6e50
Patch-mainline: v5.6-rc1
References: jsc#SLE-13430

Before we start looping over the internal TX FIFOs increase the fifo
number, but that's incorrect and causes a FIFO to be skipped.  This is
probably due to a copy and paste from the previous loop.
