wifi: iwlwifi: ensure we don't read SAR values past the limit
When we fill the SAR values, we read values from the BIOS store in the
firmware runtime object and write them into the command that we send to
the firmware.
We assumed that the size of the firmware command is not longer than the
BIOS tables. This has been true until now, but this is not really safe.
We will soon have an firmware API change that will increase the size of
the table in the command and we want to make sure that we don't have a
buffer overrun when we read the firmware runtime object.
Add this safety measure.
