[Beignet] [Patch v2 1/2] reset the variables in printf_paser to NULL.

[xionghu.luo at intel.com]

From: Luo Xionghu <xionghu.luo at intel.com>

the printfPaser variables g1Xg2Xg3 and wg_offset should be reinit
after the builder is deleted, or else the variables will be freed and
caused memory leak;
