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.
