tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() when iterating clk
commit 832e231cff476102e8204a9e7bddfe5c6154a375 upstream.
When the best clk is searched, we iterate over all possible clk.
If we find a better match, the previous one, if any, needs to be freed.
If a better match has already been found, we still need to free the new
one, otherwise it leaks.
