idr uses -1, IDR_NEED_TO_GROW and IDR_NOMORE_SPACE to communicate exception conditions internally. The return value is later translated to errno values using _idr_rc_to_errno(). This is confusing. Drop the custom ones and consistently use -EAGAIN for "tree needs to grow", -ENOMEM for "need more memory" and -ENOSPC for "ran out of ID space". Due to the weird memory preloading mechanism, [ra]_get_new*() return -EAGAIN on memory shortage, so we need to substitute -ENOMEM w/ -EAGAIN on those interface functions. They'll eventually be cleaned up and the translations will go away. This patch doesn't introduce any functional changes.
