core: ltc: fix return value in crypto API SM2 PKA decrypt
Fix calloc() failure case in core crypto API function for SM2 PKE
decryption. Prior this change the function failed but return 0/OK.
This change sets the return value to TEE_ERROR_OUT_OF_MEMORY before
reaching the function exit sequence.
Fixes: f9a78287dd12 (core: ltc: add support for SM2 PKE)
