Fix warnings/errors in ceph API tests that are present in FSCrypt.cc

src/client/FSCrypt.cc:90:6: error: variable 'olen' set but not used [-Werror,-Wunused-but-set-variable]
   90 |         int olen = 0;
      |             ^
src/client/FSCrypt.cc:91:6: error: variable 'line' set but not used [-Werror,-Wunused-but-set-variable]
   91 |         int line = 0;
      |             ^
