Re: [PATCH] Fix corruption error in rh_alloc_fixed()

There is an error in rh_alloc_fixed() of the Remote Heap code:
If there is at least one free block blk won't be NULL at the end of  
the
search loop, so -ENOMEM won't be returned and the else branch of
"if (bs == s || be == e)" will be taken, corrupting the management
structures.

Fix an error in rh_alloc_fixed() that made allocations succeed when
they should fail, and corrupted management structures.
