[PATCH 1/3] ata: libata-transport: drop the dead GSCR newline check

[shao.mingyin]

From: Shao Mingyin <shao.mingyin@xxxxxxxxxx>

SATA_PMP_GSCR_DWORDS is 128, so "SATA_PMP_GSCR_DWORDS & 3" is always
zero and the branch is dead.  The loop already terminates every fourth
dword with a newline.

No functional change.
