ibmvnic: fix miscellaneous checks

Fix the following checkpatch checks:
CHECK: Macro argument 'off' may be better as '(off)' to
avoid precedence issues
CHECK: Alignment should match open parenthesis
CHECK: multiple assignments should be avoided
CHECK: Blank lines aren't necessary before a close brace '}'
CHECK: Please use a blank line after function/struct/union/enum
declarations
CHECK: Unnecessary parentheses around 'rc != H_FUNCTION'
