ipc: remove use of seq_printf return value
commit 7f032d6ef6154868a2a5d5f6b2c3f8587292196c upstream.
The seq_printf return value, because it's frequently misused,
will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
