[PATCH 04/17] usb: host: ehci-dbg: move trailing statements to next line

[Geyslan G. Bem]

This patch fixes coding style issues reported by checkpatch concerning
to switch case statements. There are few additional changes made to fix
other coding styles issues.

These additional changes are:

 - The compound statement "({...})" on line 474 is pulled out from
   snprintf parameters.

 - On line 723 the constant "0x03" is moved to right.

Signed-off-by: Geyslan G. Bem <geyslan@xxxxxxxxx>

Notes:
    Before this patch there are 14 warnings about trailing statements that
    should be on next line. After there are still 4. These lines concern to
    a macro that will be modified to inline function in sequential patches.
    
    Tested by compilation only.
