iwlwifi: mvm: remove an extra tab

Smatch prints a static checker warning here:

    drivers/net/wireless/intel/iwlwifi/mvm/fw-dbg.c:386 iwl_dump_prph()
    warn: curly braces intended?

Curly braces are NOT intended, the extra tab was added by mistake in
commit 1a616dd2 ('iwlwifi: dump prph registers in a common place
for all transports').
