Fix the following warning observed with GCC 13.2 and -Wformat-truncation:
drivers/net/wireless/ath/ath11k/debugfs.c: In function ‘ath11k_debugfs_register’:
drivers/net/wireless/ath/ath11k/debugfs.c:1597:51: warning: ‘%d’ directive output
may be truncated writing between 1 and 3 bytes into a region of size 2 [-Wformat-truncation=]
1597 | snprintf(pdev_name, sizeof(pdev_name), "%s%d", "mac", ar->pdev_idx);
| ^~
drivers/net/wireless/ath/ath11k/debugfs.c:1597:48: note: directive argument in the range [0, 255]
1597 | snprintf(pdev_name, sizeof(pdev_name), "%s%d", "mac", ar->pdev_idx);
| ^~~~~~
drivers/net/wireless/ath/ath11k/debugfs.c:1597:9: note: ‘snprintf’ output between
5 and 7 bytes into a destination of size 5
1597 | snprintf(pdev_name, sizeof(pdev_name), "%s%d", "mac", ar->pdev_idx);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Simplify the 'snprintf()' statement as well.
