[PATCH v1 4/4] Input: psmouse - increase size of phys

[Andy Shevchenko]

When creating a physical device name in the driver the snprintf() takes
an up to 32 characters argument along with the additional 8 characters
and tries to pack this into 32 bytes array. GCC complains about that
when build with `make W=1`:

drivers/input/mouse/psmouse-base.c:1603:9: note: ‘snprintf’ output between 8 and 39 bytes into a destination of size 32
 1603 |         snprintf(psmouse->phys, sizeof(psmouse->phys), "%s/input0", serio->phys);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Increase the size to cover all possible cases.
