ceph: ensure prealloc_blob is in place when removing xattr
In __ceph_build_xattrs_blob(), if a ceph inode's extended attributes
are marked dirty, all attributes recorded in its rb_tree index are
formatted into a "blob" buffer. The target buffer is recorded in
ceph_inode->i_xattrs.prealloc_blob, and it is expected to exist and
be of sufficient size to hold the attributes.
The extended attributes are marked dirty in two cases: when a new
attribute is added to the inode; or when one is removed. In the
former case work is done to ensure the prealloc_blob buffer is
properly set up, but in the latter it is not.
Change the logic in ceph_removexattr() so it matches what is
done in ceph_setxattr(). Note that this is done in a way that
keeps the two blocks of code nearly identical, in anticipation
of a subsequent patch that encapsulates some of this logic into
one or more helper routines.
