Fix "control flow" issues found by Coverity
Logically dead code (DEADCODE)
Execution cannot reach this statement.
Assigned_value: Assigning value NULL to p here
293 char *p = NULL;
In the following conditional expression, the value of p is always NULL,
as a result, the kunmap() cannot be executed.
308 if (p)
309 kunmap(bh_result->b_page);
355 if (p)
356 kunmap(bh_result->b_page);
366 if (p)
367 kunmap(bh_result->b_page);
