iwlwifi: mvm: writing zero bytes to debugfs causes a crash
This is a static analysis fix. The warning is:
drivers/net/wireless/intel/iwlwifi/mvm/fw-dbg.c:912 iwl_mvm_fw_dbg_collect()
warn: integer overflows 'sizeof(*desc) + len'
I guess this code is supposed to take a NUL character, but if we write
zero bytes then it tries to write -1 characters and crashes.
