Subject: [PATCH v3 4/4] staging: rtl8723bs: remove unused allocation wrapper functions

All memory allocation call sites have been migrated to kernel
APIs (kmalloc, kzalloc, and skb functions). Therefore, the custom
wrapper layer is no longer necessary.

This patch removes all redundant wrapper functions and macros from
osdep_service.c and include/osdep_service.h, including unused macros
like rtw_skb_alloc_f.
