[PATCH 1/8] Input: cap11xx - clean up duplicate log and add probe error logs

[Jun Yan <jerrysteve1101@gmail.com>]

Duplicated device detection log exists at line 537 and line 542,
which brings redundant repeated kernel print messages. Drop one
redundant log entry to clean up dmesg output.

Meanwhile add missing error logs when I2C communication fails
during driver probe(), helping capture abnormal hardware access
for debug.
