Original code assumes the previous node in physical must be
ALLOCED, but other thread may free the previous node between
mm_malloc() and mm_lock(), and the original code didn't condsider
this, which will cause two adjacent free nodes situation and this
should not be happened.
This commit will merge the previous node and node if the previous
node is free to avoid the situation discribed above.

Issue:
TCP rx buffer is freed after 4-way handshake with current design.
3 socket's rx buffer might be consumed during ffmpeg switch music procedure,
and this might cause IOB exhausted.
Solution:
free TCP rx buffer immediately in tcp_close to make sure IOB won't be
exhausted.
