reiserfs: don't preallocate blocks for extended attributes
commit 54930dfeb46e978b447af0fb8ab4e181c1bf9d7a upstream.
Most extended attributes will fit in a single block. More importantly,
we drop the reference to the inode while holding the transaction open
so the preallocated blocks aren't released. As a result, the inode
may be evicted before it's removed from the transaction's prealloc list
which can cause memory corruption.
