accel/ivpu: Add bounds checks for firmware log indices
Add validation that read and write indices in the firmware log buffer
are within valid bounds (< data_size) before using them. If
out-of-bounds indices are encountered (from firmware), clamp them to
safe values instead of proceeding with invalid offsets.
This prevents potential out-of-bounds buffer access when firmware
supplies invalid log indices.
