Subject: [PATCH] USB: hcd: remove unused hcd_name variables

In the commit 10174220f55a ("usb: reduce kernel log spam on driver
registration") a lot of unneeded kernel log messages were removed, but
that caused a few build warnings to show up where the variable
`hcd_name` was being set but never used anymore.

Resolve this by just removing these variables as they are not needed
anymore
