gfs2: perform quota checks against allocation parameters
gfs2: allow quota_check and inplace_reserve to return
available instead of guessing, we
can max out quotas or the filesystem efficiently.
Bear in mind that this applies only when the requested fallocate
operation would otherwise error out with -EDQUOT or -ENOSPC without
utilizing all the blocks that might still be available.

functions may be called again requesting 'max_avail' blocks to

This patch moves some code around and fixes some corner cases that
the previous patches did not address.
This patch also fixes some trailing whitespace and removes a test

and so, the fix in gfs2_inplace_reserve() as per
1) won't work in this scenario. We need to catch and fix it sooner
in the parent dir itself (gfs2_create_inode()), before it is
copied to the new inode.

This patch makes gfs2_convert check for bad values of sb_seg_size,
sb_quota_di and sb_license_di.
In fsck.gfs2, attempts are made to correct these erroneous values.
