iwlwifi: dbg_ini: allocate dram buffer with proper flags

Browse Source 
Use the same flags we use in the legacy buffer allocation.
Missing __GFP_NOWARN will cause an unwanted warning incase
we fail to allocate.
Missing __GFP_ZERO will give a buffer initially filled with
garbage which can make debug difficult in case our wrap count is zero.
