tracing: Modify print_fields() for fields output order
Now the print_fields() print trace event fields in reverse order. Modify
it to the positive sequence.
Example outputs for a user event:
test0 u32 count1; u32 count2
Output before:
example-2547 [000] ..... 325.666387: test0: count2=0x2 (2) count1=0x1 (1)
Output after:
example-2742 [002] ..... 429.769370: test0: count1=0x1 (1) count2=0x2 (2)
