ext4_ext_grow_indepth() allocates memory chunk for "newblk" with
ext4_ext_alloc_meta(). When getblk() and bwrite() fail in this funciton,
"newblk" is not released, which will lead to a memory leak.

We should release the "newblk" with ext4_ext_blkfree() when some error
occurs to avoid the memory leak.
