[U-Boot] [PATCH] usb: f_mass_storage: Fix compile on x86

[Bryan O'Donoghue]

Compiling the f_mass_storage driver for an x86 target results in a
compilation error as set_bit and clear_bit are provided by bitops.h

Fix that now by only compiling up the local definition of set_bit and
clear_bit only if not already provided by the environment.
