lima: fix PP stream terminator size

Browse source 
PP stream terminator size seems to be 4 words, it worked with full PP
stream because we align stream beginning to 32 bytes and BO is
initialized with zeroes. But with partial PP stream it sometimes break
if for new PP stream we reuse BO that has non-zero value at this place.
