lustre: obdclass: linux: Replace uses of OBD_{ALLOC, FREE}_LARGE

Replace uses of OBD_ALLOC_LARGE by libcfs_kvzalloc and OBD_FREE_LARGE by
kvfree.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

- OBD_ALLOC_LARGE(ptr,size)
+ ptr = libcfs_kvzalloc(size, GFP_NOFS)

@@
expression ptr,size;

- OBD_FREE_LARGE(ptr, size);
+ kvfree(ptr);
