[socket] Fix RP2040 socket_delay race: don't clear wake flag before sleep

Restore the comment explaining why s_socket_woke must not be cleared
between the early-return check and the __wfe() loop, and restore the
s_socket_woke = false after the loop to consume the wake for the next
call. Both were lost during conflict resolution.
