Shyam Sunder Reddy Padira bc851db060 staging: rtl8723bs: os_dep: avoid NULL pointer dereference in rtw_cbuf_alloc 
The return value of kzalloc_flex() is used without
ensuring that the allocation succeeded, and the
pointer is dereferenced unconditionally.

Guard the access to the allocated structure to
avoid a potential NULL pointer dereference if the
allocation fails.
