uml: fix unreasonably long udelay
Currently we have a confused udelay implementation.
* __const_udelay does not accept usecs but xloops in i386 and x86_64
* our implementation requires usecs as arg
* it gets a xloops count when called by asm/arch/delay.h
Bugs related to this (extremely long shutdown times) where reported by some
x86_64 users, especially using Device Mapper.
To hit this bug, a compile-time constant time parameter must be passed - that's
why UML seems to work most times.
Fix this with a simple udelay implementation.
