[TF2] fix: remove early return in coach request check

[CosminPerRam]

Description

Early returning false skips the threshold of hours check and because of the previous checks, makes the function always return false unconditionally.

[HyperionCoding]

It's probably added to intentionally disable coaching.

[CosminPerRam]

Possible indeed, an official clarification if this is intentional would be nice to have to add a documentation comment instead (and to move the early return at the beginning to skip redundant checks).
