Input: synaptics-rmi4 - set reduced reporting mode only when requested

The previous patch "c5ccf2ad3d33 (Input: synaptics-rmi4 - switch to
reduced reporting mode)" enabled reduced reporting mode unintentionally
on some devices, if the firmware was configured with default Delta X/Y
threshold values. The result unintentionally degrade the performance of
some touchpads.

This patch checks to see that the driver is modifying the delta X/Y
thresholds before modifying the reporting mode.

Input: synaptics-rmi4 - switch to reduced reporting mode

When the distance thresholds are set the controller must be in reduced
reporting mode for them to have any effect on the interrupt generation.
This has a potentially large impact on the number of events the host
needs to process.

Currently, rmi_f11_attention() and rmi_f12_attention() functions update
the attn_data data pointer and size based on the size of the expected
size of the attention data. However, if the actual valid data in the
attn buffer is less then the expected value then the updated data
pointer will point to memory beyond the end of the attn buffer. Using
the calculated valid_bytes instead will prevent this from happening.
