[RFC PATCH 06/23] vinyl: fold vy_delete_impl

[Vladimir Davydov <vdavydov.dev@gmail.com>]

vy_delete_impl helper is only used once in vy_delete and it is rather
small so inlining it definitely won't hurt. On the contrary, it will
consolidate DELETE logic in one place, making the code easier to follow.
