Subject: [PATCH -next] ufs: remove set but not used variable 'usb3'

Fixes gcc '-Wunused-but-set-variable' warning:

fs/ufs/super.c: In function ufs_statfs:
fs/ufs/super.c:1409:32: warning: variable usb3 set but not used [-Wunused-but-set-variable]

It is not used since commmit c596961d1b4c ("ufs: fix s_size/s_dsize users")
