testsuites/validation/tx-call-within-isr.c: Address dangling pointer

Browse Source 
On the genmcf548x BSP variants, the "request" local variable was
flagged as having a pointer taken and passed to subroutines. GCC
is unable to detect that the "request" variable is removed from
the chain in an ISR. Disabled -Wdangling-pointer for the single
test function CallWithinISR().
