staging: lustre: ptlrpc: clean up whitespace around parentheses

Fix the following types of checkpatch errors and warnings to comply with
coding style:

ERROR: space required before the open parenthesis '('
ERROR: space prohibited after that open parenthesis '('
ERROR: space prohibited before that close parenthesis ')'
WARNING: space prohibited between function name and open parenthesis '('
