Nirmoy Das 8ebe2d452f drm/i915/tc: Fix -Wformat-truncation in intel_tc_port_init ...

[ Upstream commit 9506fba463 ]

Fix below compiler warning:

intel_tc.c:1879:11: error: ‘%d’ directive output may be truncated
writing between 1 and 11 bytes into a region of size 3
[-Werror=format-truncation=]
"%c/TC#%d", port_name(port), tc_port + 1);
           ^~
intel_tc.c:1878:2: note: ‘snprintf’ output between 7 and 17 bytes
into a destination of size 8
  snprintf(tc->port_name, sizeof(tc->port_name),
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    "%c/TC#%d", port_name(port), tc_port + 1);
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

v2: use kasprintf(Imre)
v3: use const for port_name, and fix tc mem leak(Imre)
