[PATCH v2 1/2] Input: ilitek_ts_i2c - avoid wrong input subsystem sync

[Emanuele Ghidoli]

From: Emanuele Ghidoli <emanuele.ghidoli@xxxxxxxxxxx>

For different reasons i2c transaction may fail or
report id message content may be wrong.
Avoid sync the input subsystem if message cannot be parsed.
An input subsystem sync without points is interpreted as
"nothing is touching the screen" while normally this is not the case.

Fixes: 42370681bd46 ("Input: Add support for ILITEK Lego Series")
