lib: fix infinite loop in __darr_in_vsprintf

`darr_avail` returns the available capacity excluding the already
existing terminating NULL byte. Take this into account when using
`darr_avail`. Otherwise, if the error length is a power of 2, the
capacity is never enough and the function stucks in an infinite loop.
