The address of a data structure member was determined before
a corresponding null pointer check in the implementation of
the function “vdec_vp9_slice_single_decode”.
Thus avoid the risk for undefined behaviour by moving the assignment
for the variable “pfc” behind some condition checks.
This issue was detected by using the Coccinelle software.
