Auto merge of #91339 - cbarrete:vecdeque-remove-grow-check, r=Mark-Simulacrum

Remove unnecessary check in VecDeque::grow

All callers already check that the buffer is full before calling
`grow()`. This is where it makes the most sense, since `grow()` is
`inline(never)` and we don't want to pay for a function call just for
that check.
It could also be argued that it would be correct to call `grow()` even
if the buffer wasn't full yet.
This change breaks no code since `grow()` is not `pub`.
