fix(freertos): Fixed bug with prvENTER/EXIT_CRITICAL_OR_MASK_ISR() macro

Browse Source 
Fixed an undiscovered bug with prvENTER_CRITICAL_OR_MASK_ISR() and
prvEXIT_CRITICAL_OR_MASK_ISR() where the `uxInterruptStatus` argument was not
used.

However, all calls of this macro provide a local `uxSavedInterruptStatus`
variable, leading to this bug being hidden.
