Subject: [PATCH] arch: blackfin: kernel: using strlcpy instead of strncpy


For NULL terminated string, need always be sure of ended by zero.

'command_line' is a static variable which will be initialized
automatically, and cmdline_init() is __init function, so need not
initialize it again, can just use strlcpy instead of strncpy.
