staging: rtl8723bs: core: avoid NULL pointer dereference in c2h_wk_callback

Browse source

kmalloc(16, GFP_ATOMIC) in c2h_wk_callback() could in theory return2
NULL, which would then be dereferenced in rtw_hal_c2h_valid().

A 16-byte allocation effectively cannot fail in practice, but add an
else continue; to the guard so the failure path exits the iteration
cleanly to make the code more robust.
