usb: f_mass_storage: Bump local buffer size in fsg_common_create_luns()

GCC (Debian 14.2.0-19) 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, although cfg->nluns is limited to FSG_MAX_LUNS (16), the compiler
doesn't realize this and complains about the buffer size.

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