MDEV-32456: incorrect result of gis function in view protocol

Browse Source 
There are 3 diff in result:
1) NULL value from SELECT
Due to incorrect truncating of the hex value, incorrect value is
written instead of original value to the view frm. This results in reading
incorrect value from frm, so eventual result is NULL.
2) 'Name_exp1' in column name (in gis.test)
This was because the identifier in SELECT is longer than 64 characters,
so 'Name_exp1' alias is also written to the view frm.
3)diff in explain extended
This was because the query plan for view protocol doesn't
contain database name. As a fix, disable view protocol for that particular
query.
