Subject: [PATCH] present: Fix missing byte swaps in sproc_present_pixmap()

sproc_present_pixmap() was missing byte swaps the variable-length
xPresentNotify array after the fixed header was not
byte-swapped at all (each entry has window and serial CARD32 fields).

Fixes: a5ac3c871219 ("present: add missing byte swapping for various fields")
