ath6kl: Unify sg_sz and buf_sz in ath6kl_sdio_alloc_prep_scat_req()
sg_sz and buf_sz are initialized and used in a mutual exclusive way. However, some versions of gcc are not smart enough to see this: drivers/net/wireless/ath/ath6kl/sdio.c: In function ‘ath6kl_sdio_alloc_prep_scat_req’: drivers/net/wireless/ath/ath6kl/sdio.c:338: warning: ‘sg_sz’ may be used uninitialized in this function Unify the sg_sz and buf_sz variables into a single size variable to kill the compiler warning.
