Subject: [PATCH v2 1/2] Staging: rts5208: Replace strncpy() with strscpy()

warning found by checkpatch.pl script.I replaced the usage of strncpy()
with strscpy() in the code(line 524) for the buf buffer to improve
string copying.This is appropriate since strscpy() is used when you want
to copy a NUL-terminated string and the destination buffer requires
trailing NUL-padding.
