wangbowen6 81d37d0320 mm_memalign: avoid two adjacent free nodes situation. 
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.
