Subject: [PATCH 2/3] mke2fs: add get_uint_from_profile to mke2fs.c

We can set flex_bg count only up to 2^30 with profile
because get_int_from_profile can handle it to 2^31-1.
Add get_uint_from_profile to read unsigned int value
so that mke2fs with profile can handle up to 2^31 flex_bg same as -G option.
