printk: Use prb_first_seq() as base for 32bit seq macros
[ Upstream commit 90ad525c2d9a8a6591ab822234a94b82871ef8e0 ]
Note: This change only applies to 32bit architectures. On 64bit
architectures the macros are NOPs.
Currently prb_next_seq() is used as the base for the 32bit seq
macros __u64seq_to_ulseq() and __ulseq_to_u64seq(). However, in
a follow-up commit, prb_next_seq() will need to make use of the
32bit seq macros.
Use prb_first_seq() as the base for the 32bit seq macros instead
because it is guaranteed to return 64bit sequence numbers without
relying on any 32bit seq macros.
