Masking of core mask was incorrect. Instead of using 1U for shifting, it
should be using 1LU as the result is assigned to uint64.
CID 375859: Potentially overflowing expression "1U << app_main_core" with
type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic,
and then used in a context that expects an expression of type "uint64_t"
(64 bits, unsigned).
