tcm_qla2xxx: Handle malformed wwn strings properly
If we make a variable an unsigned int and then expect it to be < 0 on
a bad character, we're going to have a bad time. Fix the tcm_qla2xxx
code to actually notice if hex_to_bin() returns a negative variable.
This was detected by the compiler warning:
scsi/qla2xxx/tcm_qla2xxx.c: In function ‘tcm_qla2xxx_npiv_extract_wwn’:
scsi/qla2xxx/tcm_qla2xxx.c:148:3: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]
