[PATCH v1 1/1] usb: f_mass_storage: Bump local buffer size in fsg_common_create_luns()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

GCC is not happy about the buffer size:

drivers/usb/gadget/function/f_mass_storage.c:2970:48: error: ‘%d’ directive output may be truncated writing between 1 and 9 bytes into a region of size 5 [-Werror=format-truncation=]

Bump the size to get it enough for all possible values.

Note, the existing comment is wrong as size 8 for the whole buffer doesn't
cover 100 mil numbers, hence drop it altogether.

Fixes: b27c08c953e9 ("usb: gadget: f_mass_storage: create lun creation helpers for use in fsg_common_init")
