src: Change parameters of SNPRINTF_BUFFER_SIZE macro.
SNPRINTF_BUFFER_SIZE() macro declaration and definition is changed so that it accepts three arguments ret, remain and offset. Parameters size and len are not required instead parameter remain keeps track of available space in the buffer. Signed-off-by: Varsha Rao <rvarsha016@gmail.com>
