Subject: [PATCH] gadget: make USB_CONFIGFS_MASS_STORAGE depend on BLOCK

From: Randy Dunlap <rdunlap@...radead.org>

Make USB_CONFIGFS_MASS_STORAGE depend on BLOCK just like the other
gadget MASS_STORAGE options do.  This fixes the following build errors
that occur when BLOCK is not enabled:

drivers/usb/gadget/storage_common.c: In function 'fsg_lun_open':
drivers/usb/gadget/storage_common.c:241:3: error: implicit declaration of function 'bdev_logical_block_size' [-Werror=implicit-function-declaration]
drivers/usb/gadget/storage_common.c:242:3: error: implicit declaration of function 'blksize_bits' [-Werror=implicit-function-declaration]
