ethernet: ucc_geth: remove {rx,tx}_glbl_pram_offset from struct ucc_geth_private
These fields are only used within ucc_geth_startup(), so they might as
well be local variables in that function rather than being stashed in
struct ucc_geth_private.
Aside from making that struct a tiny bit smaller, it also shortens
some lines (getting rid of pointless casts while here), and fixes the
problems with using IS_ERR_VALUE() on a u32 as explained in commit
800cd6fb76f0 ("soc: fsl: qe: change return type of cpm_muram_alloc()
to s32").
