If a transaction exists, release it if possible. If `alpm_trans_release` errors out (returns a non-zero), return a -1 in `alpm_release`. This patch addresses the following issue observed in `pyalpm`: https://gitlab.archlinux.org/archlinux/pyalpm/-/issues/25, where `pyalpm` ends up raising twice due to an unexpected failure during handle release, while a transaction is locked. This is a modified version of https://patchwork.archlinux.org/project/pacman/patch/20200119191833.581492-1... and is a derivation of his (Morganamilo's) work.
