[PATCH] fs/reiserfs/inode: remove dead code in _get_block_create_0()

[zengjx95]

From: Zeng Jingxiang <linuszeng@xxxxxxxxxxx>

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);
