Ye Bin 30e95fdc96 ext4: allocate extended attribute value in vmalloc area ...

commit cc12a6f25e upstream.

Now, extended attribute value maximum length is 64K. The memory
requested here does not need continuous physical addresses, so it is
appropriate to use kvmalloc to request memory. At the same time, it
can also cope with the situation that the extended attribute will
become longer in the future.
