Fix wrong transmuted type in TaskPool::scope_with_executor_inner
(#11455)
# Objective
#8219 changed the target type of a `transmute` without changing the one
transmuting from ([see the relevant
diff](55e9ab7c92 (diff-11413fb2eeba97978379d325353d32aa76eefd0af0c8e9b50b7f394ddfda7a26R351-R355)
)),
making them incompatible. This PR fixes this by changing the initial
type to match the target one (modulo lifetimes).
## Solution
Change the type to be transmuted from to match the one transmuting into
(modulo lifetimes)
