um: Eliminate null test after alloc_bootmem
alloc_bootmem function never returns NULL. Thus a NULL test after a
call to this function is unnecessary.
The Coccinelle semantic patch used to make this change is follows:
@@
expression E;
statement S;
@@
E =
alloc_bootmem(...)
... when != E
- if (E == NULL) S
