Subject: [PATCH] e1000: fix missing link interrupt check brackets
The device lsc interrupt check has a misleading whitespace around it which
can be improved by adding appropriate braces to the check. Since the ret
variable was checked after previous assignment, this introduces no functional
change.

The test application calls printf(...) with the suite->suite_name argument.
The intent (based on whitespace) in the printf is to check suite->suite_name
first and then apply the printf. This doesn't happen due to missing brackets.
