wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs

Browse source

The loop counter 'count' was declared as u8 while num_pc is u32.
If firmware advertises more than 255 PC entries the counter wraps
back to zero and the loop never terminates potentially causing an
infinite loop or reading past the allocated pc_data array.

Change the declaration to u32 to match num_pc.
