LU-6763 lnet: test for sk_sleep presence in compact-2.6.h

Like Lustre external infiniband stacks create a compability
layer to handle various distributions and kernel versions.
Due to this besides the linux kernel sk_sleep can also be
defined by the external infiniband stack. We need to examine
the infiniband stack's headers to see if sk_sleep is available
there as well.
