Handle any invalidate_inodes_check prototype.
In the comments of commit 723aa3b0c2eed070f7eeadd2ce2d87f46da6d0f8,
mmatuska reported that the test for invalidate_inodes_check() is broken
if invalidate_inodes() takes two arguments.
This patch fixes the issue by resorting to another approach for
detecting invalidate_inodes_check(): is simply checks if
invalidate_inodes is defined as a macro. If it is, then it concludes
that invalidate_inodes_check() is available. This will continue to work
even if the prototype of invalidate_inodes_check() changes over time.

Closes #148
