[PATCH rtw-next 6/6] wifi: rtlwifi: remove byte(), packet_get_type() and FILL_OCTET_STRING()

[Rishik Yechuri <epicrishik@gmail.com>]

byte() in wifi.h has a single user. rtl8192se takes the low byte of the
firmware header version with it, which is just a mask. Open code that
as & 0xff.

packet_get_type() and FILL_OCTET_STRING() have no users at all.
packet_get_type() also refers to EF1BYTE(), which no longer exists in
the driver, so it could not be used even if someone wanted to.

Remove the three macros.

No functional change intended.
