[PATCH] staging: rtl8192e: Clean up the tests on the results of functions that return NULL on failure.

[pooja.shamili]

Functions returning NULL as a return value on failure can be tested for
as !x, NULL == x or x == NULL. As !x is commonly used, all the tests
need to be modified to use !x for a consistent coding style. In this
patch, the function kzalloc is considered.
