Return an error if a field's mask is neither full nor empty. When a mask
is only partial the field is not being used for rule programming but it
gives a wrong impression it is used. Fix by returning an error on any
partial mask to make it clear they are not supported.
The ip_ver assignment is moved earlier in code to allow using it in
iavf_validate_fdir_fltr_masks.

The maximum number (2) of flex-byte support is derived from ethtool
use-def data size (8 byte).
Change the magic number 2 to macro definition, and add the comment to
track the design thinking, so the code is clear and easily maintained.

Flex-bytes allows for packet matching based on an offset and value. This
is supported via the ethtool user-def option.
The user-def 0xAAAABBBBCCCCDDDD: BBBB is the 2 byte pattern while AAAA
corresponds to its offset in the packet. Similarly DDDD is the 2 byte
pattern with CCCC being the corresponding offset. The offset ranges from
0x0 to 0x1F7 (up to 504 bytes into the packet). The offset starts from
the beginning of the packet.
This feature can be used to allow customers to set flow director rules
for protocols headers that are beyond standard ones supported by ethtool
(e.g. PFCP or GTP-U).
Like for matching GTP-U's TEID value 0x10203040:
ethtool -N ens787f0v0 flow-type udp4 dst-port 2152 \
user-def 0x002e102000303040 action 13
