ata: libata-eh: Remove unnecessary snprintf arithmetic
Remove an unnecessary arithmetic operation from a call to snprintf, because the size parameter of snprintf includes the trailing null space. Also, initialize the buffer on definition instead of a memset call. Signed-off-by: Levente Kurusa <levex@linux.com> Signed-off-by: Tejun Heo <tj@kernel.org>
