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: 852f0048f3ea ("make guest_memfd require uncoordinated discard")
