[Crash-utility] fix gdb_get_datatype cannot handle integer type

[Lei Wen]

Hi Dave,

Current when pass integer type to gdb_get_datatype in crash, it would return
req->typecode=0 and req->length=0.

As it only allow TYPE_CODE_ENUM to be passed. here is a patch for fixing it.
Do you think it could be merged?
