xfs: fallback to vmalloc for large buffers in xfs_compat_attrlist_by_handle
Shamelessly copied from dchinner's: ad650f5b xfs: fallback to vmalloc for large buffers in xfs_attrmulti_attr_get xfsdump uses a large buffer for extended attributes, which has a kmalloc'd shadow buffer in the kernel. This can fail after the system has been running for some time as it is a high order allocation. Add a fallback to vmalloc so that it doesn't require contiguous memory and so won't randomly fail while xfsdump is running. This was done for xfs_attrlist_by_handle but xfs_compat_attrlist_by_handle (the 32-bit version) needs the same attention.
