RAS/CEC: Use the right length for "cec_disable"

parse_cec_param() compares a string with "cec_disable" using only 7
characters of the 11-character-long string.

The proper solution for this would be:

#define CEC_DISABLE  "cec_disable"

strncmp(str, CEC_DISABLE, strlen(CEC_DISABLE))

but when comparing a string against a string constant strncmp() has no
advantage over strcmp() because the comparison is guaranteed to be bound by
the string constant. So just replace str strncmp() with strcmp().

[ tglx: Made it use strcmp and updated the changelog ]
