ata: libata-eh: Fix compilation warning in ata_eh_link_report()
The 6 bytes length of the tries_buf string in ata_eh_link_report() is
too short and results in a gcc compilation warning with W-!:
drivers/ata/libata-eh.c: In function ‘ata_eh_link_report’:
drivers/ata/libata-eh.c:2371:59: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 4 [-Wformat-truncation=]
2371 | snprintf(tries_buf, sizeof(tries_buf), " t%d",
| ^~
drivers/ata/libata-eh.c:2371:56: note: directive argument in the range [-2147483648, 4]
2371 | snprintf(tries_buf, sizeof(tries_buf), " t%d",
| ^~~~~~
drivers/ata/libata-eh.c:2371:17: note: ‘snprintf’ output between 4 and 14 bytes into a destination of size 6
2371 | snprintf(tries_buf, sizeof(tries_buf), " t%d",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2372 | ap->eh_tries);
| ~~~~~~~~~~~~~
Avoid this warning by increasing the string size to 16B.
