msm: vidc: Enable error recovery by default 



Error recovery is enabled by default & it will get triggered
for all sys error reported by video firmware.

For debugging purpose it can be disabled as:
    1. disable error recovery for noc error:
       echo 1 > /d/msm_vidc/disable_err_recovery
    2. disable error recovery for non-noc error:
       echo 2 > /d/msm_vidc/disable_err_recovery
    3. disable error recovery for all cases
       echo 3 > /d/msm_vidc/disable_err_recovery
