fs/qnx4: decrement sizeof size in strncmp

Author: Julia Lawall <julia@diku.dk>

As an identical match is wanted in this case, strcmp can be used instead.

The semantic match that lead to detecting this problem is as follows:

// 
@@
expression foo;
constant char *abc;
@@

*strncmp(foo, abc, sizeof(abc))
//
