Anton Moryakov 21edd76ade linux_compat: fix NULL pointer dereference in get_mem() ...

Add NULL check after memalign() call in get_mem() to prevent
potential NULL pointer dereference (CWE-476).

The function memalign() can return NULL on allocation failure.
Dereferencing the returned pointer without checking for NULL
may cause a crash in low-memory conditions.

Changes:
- Add NULL check after memalign() allocation
- Return NULL on failure, consistent with function semantics

This fixes the static analyzer warning:
  linux_compat.c:34: dereference of memalign return value without NULL check
