idr: Fix an infinite loop issue
* idr routines were doing an infinite loop when the array was full but
element
#0 was still free
* Because allocations start at 1, the low bound was not being taken account
of
in idr_find_free(), causing an infinite loop
* idr_get_new_above() couldn't allocate an id >= 1 and idr_pre_get()
thought it
didn't have to expand because id #0 was available
