EHCI: fix port reset reporting
Commit b416191a (Fix EHCI port reset.) didn't move the code that checked for successful clearing of the port reset bit from ehci_submit_root(), relying on wait_ms() call instead. The mentioned code also erroneously reported port reset state when the reset was already completed. Signed-off-by: NSergei Shtylyov <sshtylyov@mvista.com>
