From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
There are two final hunks of code that are only built
if SDIO_DYNAMIC_ALLOC_MEM is defined however this is never
defined and if it was the code would lead to dereferencing
an uninitialized pointer oldmem. It appears that a previous
commit 1babeb0c3e59 ("Staging: rtl8723bs: Remove dead code")
removed some of the dead code but not all of it. Clean this
up by removing the final hunks.
