usb: [ARM] fix unresolved err() reference in host/ohci-pxa27x.c

Commit bac632462057c62173d12af06da339e158736ef2 (usb-next)

    "USB: remove err() macro"

was preceeded by a tree-wide cleanup of users, however this
one squeaked through the cracks because it had whitespace
between the function name and the bracket for the args.

Map it onto dev_err, just like all the "pre-commits" made
in advance of bac632462057, such as the example seen in
the commit 603f30bf411043eb54c2c4af68d39f5858ef1685:

    "USB: ohci-xls.c: remove err() usage"

Build tested with the ARM magician_defconfig settings.
