PM / devfreq: Fix buffer overflow in trans_stat_show

Fix buffer overflow in trans_stat_show().

Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE.

Add condition checking if we are exceeding PAGE_SIZE and exit early from loop. Also add at the end a warning that we exceeded PAGE_SIZE and that stats is disabled.

Return -EFBIG in the case where we don't have enough space to write the full transition table.
