[FM] Insufficient sd card space toast message is displayed

    Launch FM radio with no sd card -> From menu navigate to
    FM recorder -> Tap on record option and observe => Observe
    that insufficient sd card space message is displayed but it
    is not prompting to insert the card.

    The fix is to prompt to insert sd card.
