xen/arm: Correct the opcode for BUG_INSTR on arm32

A 0 was forgotten when the arm32 BUG instruction opcode has been added in commit
3e802c6ca1fb9a9549258c2855a57cad483f3cbd "xen/arm: Correctly support WARN_ON".

This will result to use a valid instruction (mcreq 0, 3, r0, cr15, cr0, {7}),
and inhibit usage of BUG/WARN_ON and co.
