ext4: Fix initalization of s_flex_groups
The s_flex_groups array should have been initialized using atomic_add
to sum up the free counts from the block groups that make up a
flex_bg. By using atomic_set, the value of the s_flex_groups array
was set to the values of the last block group in the flex_bg.
The impact of this bug is that the block and inode allocation
algorithms might not pick the best flex_bg for new allocation.
Thanks to Damien Guibouret for pointing out this problem!
