[ Upstream commit e6344c060209ef4e970cac18adeac1676a2a73cd ]

In commit 79f033f6f229 ("iwlwifi: dbg: don't limit dump decisions
to all or monitor") we changed the code to pass around a bitmap,
but in the monitor_only case, one place accidentally used the bit
number, not the bit mask, resulting in CSR and FW_INFO getting
dumped instead of monitor data. Fix that.
