bcachefs: fix trans->mem realloc in __bch2_trans_kmalloc
The old code doesn't consider the mem alloced from mempool when call
krealloc on trans->mem. Also in bch2_trans_put, using mempool_free to
free trans->mem by condition "trans->mem_bytes == BTREE_TRANS_MEM_MAX"
is inaccurate when trans->mem was allocated by krealloc function.
Instead, we use used_mempool stuff to record the situation, and realloc
or free the trans->mem in elegant way.
Also, after krealloc failed in __bch2_trans_kmalloc, the old data
should be copied to the new buffer when alloc from mempool_alloc.
