IB/cma: use strlcpy() instead of strncpy()

drivers/infiniband/core/cma_configfs.c: In function 'make_cma_dev':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 64 equals destination size [-Wstringop-truncation]

We need to use strlcpy() to make sure the string is nul-terminated.
