Subject: [PATCH] Bug#14653504  CRASH WHEN TRUNCATING PARTITIONS FROM A VIEW!

ANALYSIS
--------

When we open the view using open_new_frm() ,it doesnt set the
table-list->table variable and any access to table_list->table
will cause a crash.

FIX
---

Added a check during execution of the alter partition to return
error if table is view.
