This reverts commit 9ed4f91628737c820af6a1815b65bc06bd31518f.

The commit introduced a regression that over read the ie with
the padding.

- the expected IE information

ath10k_pci 0000:03:00.0: found firmware features ie (1 B)
ath10k_pci 0000:03:00.0: Enabling feature bit: 6
ath10k_pci 0000:03:00.0: Enabling feature bit: 7

ath10k_pci 0000:03:00.0: 00000000: c0 00 00 00 00 00 00 00

- the wrong IE with padding is read (0x77)
