lib: add error checking to hex2bin
hex2bin converts a hexadecimal string to its binary representation.
The original version of hex2bin did not do any error checking. This
patch adds error checking and returns the result.
Changelog v1:
- removed unpack_hex_byte()
- changed return code from boolean to int
Changelog:
- use the new unpack_hex_byte()
- add __must_check compiler option (Andy Shevchenko's suggestion)
- change function API to return error checking result
(based on Tetsuo Handa's initial patch)
