The passed dso_id is copied and so is never an out argument. Remove
its mutability.

* The dso__data_* external interface provides following functions:
* dso__data_get_fd
* dso__data_put_fd
* dso__data_close
* dso__data_size
* dso__data_read_offset
* dso__data_read_addr
* dso__data_write_cache_offs
* dso__data_write_cache_addr
*
* Please refer to the dso.c object code for each function and
* arguments documentation. Following text tries to explain the
* dso file descriptor caching.
*
* The dso__data* interface allows caching of opened file descriptors
* to speed up the dso data accesses. The idea is to leave the file
* descriptor opened ideally for the whole life of the dso object.
*
* The current usage of the dso__data_* interface is as follows:
*
* Get DSO's fd:
* int fd = dso__data_get_fd(dso, machine);
* if (fd >= 0) {
* USE 'fd' SOMEHOW
* dso__data_put_fd(dso);
* }
*
* Read DSO's data:
* n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE);
* n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE);
*
* Eventually close DSO's fd:
* dso__data_close(dso);
*
* It is not necessary to close the DSO object data file. Each time new
* DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once
* it is crossed, the oldest opened DSO object is closed.
*
* The dso__delete function calls close_dso function to ensure the
* data file descriptor gets closed/unmapped before the dso object
* is freed.
*
* TODO
