generic/310: slightly improve check for dmesg error

The 'grep -c "error"' check was causing false positive results for
cifs.ko when running it with 'echo 1 > /proc/fs/cifs/cifsFYI'.

That is, the test would fail when cifs.ko prints out a non-error
message like this:

  [ 2320.903987] fs/cifs/smb2maperror.c: Mapping SMB2 status code 0x80000006 to POSIX err -61
