description:
lint: fix enum type in the lexical analysis part

Detected by Clang, reported by riastradh:

> scan.l:144:29: error: implicit conversion from enumeration type
>   'tspec_t' to different enumeration type 'op_t'
> return operator(T_ASTERISK, NOTSPEC);
>        ~~~~~~~~             ^~~~~~~

and by lint as well, with a less detailed and less helpful message:

> scan.l(144): warning: enum type mismatch, arg #2 [156]

Since scan.c is generated from scan.l, it is not included in the default
"make lint" though.

The value of these two constants is the same, furthermore that value is
never actually used in the code, therefore no functional change.
