xsysace: Fix dereferencing of cf_id after hd_driveid removal
Commit 4aaf2fec718f6fbf38668edf733a0ab09a49cab1 (xsysace: make it
'struct hd_driveid'-free) converted the cf_id member of 'struct
ace_device' from a 'struct hd_driveid' to a u16 array. However,
references to the base of the structure were still using the '&'
operator. When the address was used with the ata_id_u32() macro, the
compiler used the size of the entire array instead of sizeof(u16) to
calculate the offset from the base address.
This patch removes the use of the '&' operator from all references of
cf_id to fix the bug and remove future confusion.
