Subject: thunderbolt: No need to warn if NHI hop_count != 12 or hop_count != 32
Git-commit: 177aa362eb92ab8bd350a0642b66252db24b6140
Patch-mainline: v5.9-rc1
References: jsc#SLE-14130

While Intel hardware typically has hop_count (Total Paths in the spec)
12 the USB4 spec allows this to be anything between 1 and 21 so no need
to warn about this. Simply log number of paths at debug level.
