Caleb Sander Mateos 82dadc8a49 io_uring/rsrc: take unsigned index in io_rsrc_node_lookup() 
io_rsrc_node_lookup() takes a signed int index as input and compares it
to an unsigned length. Since the signed int is implicitly cast to an
unsigned int for the comparison and the length is bounded by
IORING_MAX_FIXED_FILES/IORING_MAX_REG_BUFFERS, negative indices are
already rejected on architectures where int is at least 32 bits. Make
this a bit clearer and avoid compiler warnings for comparisons of
signed and unsigned values by taking an unsigned int index instead.
