Zhenzhong Duan 644a52778a system/physmem: use return value of ram_block_discard_require() as errno 
When ram_block_discard_require() fails, errno is passed to error_setg_errno().
It's a stale value or 0 which is unrelated to ram_block_discard_require().

As ram_block_discard_require() already returns -EBUSY in failure case,
use it as errno for error_setg_errno().

Fixes: 852f0048f3 ("make guest_memfd require uncoordinated discard")
