[PATCH 3/3] scsi: qedf: Axe a few useless lines of code

[Christophe JAILLET]

Simplify a bit this file a remove a few lines of code:
   - keep function parameters on the same line
   - remove unneeded return at the end of a function that return void
   - remove duplicated and useless empty lines
   - remove unneeded {} when there is only one statement
   - remove a few () around 'qedf->dbg_ctx' so that we can...
   - ... merge a few messages that were split on 2 lines

Many more clean-up could be done to improve readability in this file.
The above few steps have the advantage to also reduce the number of LoC.
Anyway, that's mostly a matter of taste.
