From: Amitkumar Karwar <akarwar@xxxxxxxxxxx> While updating 'left_len' in each iteration, we should subtract last TLV length not the accumulated length of TLVs parsed till now. This bug in parsing logic is exposed by newer firmware which adds two TLVs in GET_HW_SPEC command response. Earlier firmwares used to add only one TLV.
