lib: sbi: Refine the way to construct platform features
sbi_platform_get_features_str() uses sbi_snprintf() to construct the
features_str. However, it passes the wrong length value (i.e., the nfstr),
which should be (nfstr-offset) as the starting point of str (i.e.,
features_str + offset) changes.
This commit also checks the return value of snprintf, and handles the
corner case that the string buffer is full.
