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.

f769108424 UBIFS: correct orphan deletion order
The debug function that checks orphans, does so using the
TNC mutex. That means it will not see a correct picture
if the inode is removed from the orphan tree before it is
removed from TNC.

de94eb558b UBIFS: optimize deletions
Every time anything is deleted, UBIFS writes the deletion inode
node twice - once in 'ubifs_jnl_update()' and the second time in
'ubifs_jnl_write_inode()'. However, the second write is not needed
if no commit happened after 'ubifs_jnl_update()'. This patch
checks that condition and avoids writing the deletion inode for
the second time.

fd6c6b51e3 UBIFS: remove another unneeded function parameter
The 'last_reference' parameter of 'pack_inode()' is not really
needed because 'inode->i_nlink' may be tested instead. Zap it.

1f28681ad3 UBIFS: remove unneeded function parameter
Simplify 'ubifs_jnl_write_inode()' by removing the 'deletion'
parameter which is not really needed because we may test
inode->i_nlink and check whether this is a deletion or not.
