Increase the size of the string buffer to avoid potential truncation in
pci_endpoint_test_probe().
This fixes the following build warning when compiling with W=1:
drivers/misc/pci_endpoint_test.c:29:49: note: directive argument in the range [0, 2147483647]
29 | #define DRV_MODULE_NAME "pci-endpoint-test"
| ^~~~~~~~~~~~~~~~~~~
drivers/misc/pci_endpoint_test.c:998:38: note: in expansion of macro ‘DRV_MODULE_NAME’
998 | snprintf(name, sizeof(name), DRV_MODULE_NAME ".%d", id);
| ^~~~~~~~~~~~~~~
drivers/misc/pci_endpoint_test.c:998:9: note: ‘snprintf’ output between 20 and 29 bytes into a destination of size 24
998 | snprintf(name, sizeof(name), DRV_MODULE_NAME ".%d", id);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
