Avoid using printk_ratelimit() in many places because:
  - many were error messages reporting broken hardware (it's useful to
    get all of these).
  - the message itself wasn't useful so the message has been removed.

IOGear firmware versions >= 1.4.12224 fail to be downloaded because of a
spurious (and harmless) RCEB received after the download notification. This
patch handles this RCEB and keeps compatibility with future versions that might
not emit this RCEB.

i1480_rceb_check() is reused to check for the RCEB. It is also refactored with
improved comments and reused in another place in mac.c where the checking was
being duplicated.

This patch was tested on both i1480 and GUWA100U HWAs, with all firmware
versions currently available.

Some hardware/firmware combinations (most notably an IOGear HWA using the i1480
firmware) kill the host controller after issuing a GET_MAC_PHY_INFO command.
Removing this check seems harmless otherwise.

The patch fixes the issue where the HC is killed, showing the message:

ehci_hcd 0000:00:1d.7: HC died; cleaning up

After this error, USB comes back only after reloading the ehci_hcd module.
