usb: gadget: Remove set but not used variable 'opts' in msg_do_config

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

drivers/usb/gadget/legacy/mass_storage.c: In function msg_do_config:
drivers/usb/gadget/legacy/mass_storage.c:108:19: warning: variable opts set but not used [-Wunused-but-set-variable]

It is not used since commit f78bbcae86e6 ("usb: f_mass_storage:
test whether thread is running before starting another")
