rpmsg: qcom: glink: replace strncpy() with strscpy_pad()
The use of strncpy() is considered deprecated for NUL-terminated
strings[1]. Replace strncpy() with strscpy_pad(), to keep existing
pad-behavior of strncpy, similarly to commit 08de420a8014 ("rpmsg:
glink: Replace strncpy() with strscpy_pad()"). This fixes W=1 warning:
In function ‘qcom_glink_rx_close’,
inlined from ‘qcom_glink_work’ at ../drivers/rpmsg/qcom_glink_native.c:1638:4:
drivers/rpmsg/qcom_glink_native.c:1549:17: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation]
1549 | strncpy(chinfo.name, channel->name, sizeof(chinfo.name));
