Remove an unnecessary allocation.
According to SUS3: If the value of n is zero on a call to snprintf(), nothing shall be written, the number of bytes that would have been written had n been sufficiently large excluding the terminating null shall be returned, and s may be a null pointer. git-svn-id: http://opkg.googlecode.com/svn/trunk@583 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358
