[XEN] Fix bitops inline asm to specify that memory is clobbered.
Necessary because the modified word may not be the one directly
addressed by the memory parameter (since the parameter actually
points at an array, not a scalar value).

The change to set_bit/__set_bit is reported to fix an issue
on x460 hardware, as reported (and this fix suggested) by
Ryan Harper <ryanh@us.ibm.com>
