Artem Bityutskiy c78c7e35a4 UBIFS: xattr bugfixes
Xattr code has not been tested for a while and there were
serveral bugs. One of them is using wrong inode in
'ubifs_jnl_change_xattr()'. The other is a deadlock in
'ubifs_setxattr()': the i_mutex is locked in
'cap_inode_need_killpriv()' path, so deadlock happens when
'ubifs_setxattr()' tries to lock it again.

Thanks to Zoltan Sogor for finding these bugs.

Zoltan Sogor 5acd6ff8ac UBIFS: fix budgeting request alignment in xattr code
Data length has to be aligned in the budgeting request. Code
in xattr.c did not do this.

Artem Bityutskiy dab4b4d2f9 UBIFS: align inode data to eight
UBIFS aligns node lengths to 8, so budgeting has to do the
same. Well, direntry, inode, and page budgets are already
aligned, but not inode data budget (e.g., data in special
devices or symlinks). Do this for inode data as well.
Also, add corresponding debugging checks.
