[Benchmark App] Prioritize the config for device given in CLI when mu…

…ltiple are available (openvinotoolkit#26837)

### Details:
- In the case reported in the ticket the config was given for a device
`BATCH:GPU.1(128)`, which was also specified in the CLI as `-d
BATCH:GPU.1(128)`
- The previous code first found `BATCH:GPU.1(128)` as an available
device and assigned the config correctly, but afterwards it also found
`BATCH` device and overwrote the `device_config` variable with incorrect
value
 - Prioritizing the device given in the CLI solves the issue
