xhci: Don't show warning for reinit on known broken suspend

stable inclusion
from stable-v5.10.150
commit cc952e3bf61cf83e51dab80aba656da22dbc6d00
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA

--------------------------------

[ Upstream commit 484d6f7a ]

commit 8b328f80 ("xhci: re-initialize the HC during resume if HCE was
set") introduced a new warning message when the host controller error
was set and re-initializing.

This is expected behavior on some designs which already set
`xhci->broken_suspend` so the new warning is alarming to some users.

Modify the code to only show the warning if this was a surprising behavior
to the XHCI driver.
