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

[ Upstream commit 4e7dd3053c17bd37023ee126abd233c5b1625faa ]

commit 182864ace1e4 ("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.
