ide-floppy: fix most of the remaining checkpatch.pl issues

such as
ERROR: switch and case should be at the same indent
ERROR: need spaces around that '=' (ctx:VxV)
ERROR: trailing statements should be on next line
WARNING: no space between function name and open parenthesis '('
WARNING: printk() should include KERN_ facility level
ERROR: That open brace { should be on the previous line
ERROR: use tabs not spaces
ERROR: do not use assignment in if condition
WARNING: braces {} are not necessary for single statement blocks
ERROR: need space after that ',' (ctx:VxV)
WARNING: line over 80 characters
ERROR: do not use assignment in if condition
...
and so on.
