Proton/lsteamclient/steamclient_main.c
Eduard Permyakov d6aec09c05 lsteamclient: Fix forwarding incorrect result for certain path-related operations. 
The SteamAPI may return non-zero values even when a NULL pointer is
passed in for the target path buffer. For example, GetAppInstallDir
will still return the required size of the distination buffer.

Since api_result is the length of the Windows path, it is not completely
safe to return it directly, since the corresponding UNIX path may have
more characters. Without access to the original Windows path, we cannot
make a conversion to determine how many characters the UNIX path will
have. So just resort to returning a safe upper bound value.
