ring-buffer: remove type parameter from rb_reserve_next_event
The rb_reserve_next_event is only called for the data type (type = 0).
There is no reason to pass in the type to the function.
Before:
text data bss dec hex filename
16554 24 12 16590 40ce kernel/trace/ring_buffer.o
After:
text data bss dec hex filename
16538 24 12 16574 40be kernel/trace/ring_buffer.o
[ Impact: cleaner, smaller and slightly more efficient code ]
