Input: i8042 - downgrade selftest error message to dbg()

On a "really fragile" laptop I noticed a single
    i8042.c: i8042 controller selftest failed. (0x1 != 0x55)

error in the log. But there's no reason to print this message at
KERN_ERR level each time that loop fails, especially since the message
telling about the overall selftest failure is printed at KERN_INFO level
(on X86).

Add an actual error message for non-X86 systems, where a selftest
failure is (apparently) more serious. Remove a space in an another error
message.
