um: net: Eliminate NULL test after alloc_bootmem

Browse source 
alloc_bootmem and related functions never return NULL. Thus a NULL
test or memset after calls to these functions is unnecessary.

The following Coccinelle semantic patch was used for making the change:

@@
expression E;
statement S;
@@

E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...)
... when != E
- if (E == NULL) S
