libtracefs: Fix compiler -Wmemsize-comparison warning
Fixes the following clang warning:
utest/tracefs-utest.c:828:75: error: size argument in 'strncmp' call is a comparison [-Werror,-Wmemsize-comparison]
(!save_debug || strncmp(save_debug, save_tracing, strlen(save_debug) != 0)))
~~~~~~~~~~~~~~~~~~~^~~~
utest/tracefs-utest.c:828:22: note: did you mean to compare the result of 'strncmp' instead?
(!save_debug || strncmp(save_debug, save_tracing, strlen(save_debug) != 0)))
^ ~
)
utest/tracefs-utest.c:828:56: note: explicitly cast the argument to size_t to silence this warning
(!save_debug || strncmp(save_debug, save_tracing, strlen(save_debug) != 0)))
^
(size_t)( )
