UBIFS: remove an unneeded check

In 'ubifs_recover_size()' we have an "if (!e->inode && c->ro_mount)" statement.
But if 'c->ro_mount' is true, then '!e->inode' must always be true as well. So
we can remove the unnecessary '!e->inode' test and put an
'ubifs_assert(!e->inode)' instead.

This patch also removes an extra trailing white-space in a debugging print,
as well as adds few empty lines to 'ubifs_recover_size()' to make it a bit more
readable.
