If the function parse_u64() fails, we jump to return, thus leaking
the memory just allocated in 'v'.
Issue identified by clang.
Move earlier the call to parse_u64() and the associated test,
before memory allocation.
While there, fix a possible NULL pointer dereferencing in case the
calloc() fails, by testing for allocation failure.
