commit 34d7f603b93be0ac38c2464219f5a2795d76c8ee

xfs: Don't keep silent if sunit/swidth can not be changed via mount
As per the mount man page, sunit and swidth can be changed via
mount options. For XFS, on the face of it, those options seems
works if the specified alignments is properly, e.g.
# mount -o sunit=4096,swidth=8192 /dev/sdb1 /mnt
# mount | grep sdb1
/dev/sdb1 on /mnt type xfs (rw,sunit=4096,swidth=8192)
However, neither sunit nor swidth is shown from the xfs_info output.
# xfs_info /mnt
meta-data=/dev/sdb1 isize=256 agcount=4, agsize=262144 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=1048576, imaxpct=25
= sunit=0 swidth=0 blks
^^^^^^^^^^^^^^^^^^^^^^^^^^
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
The reason is that the alignment can only be changed if the relevant
super block is already configured with alignments, otherwise, the
given value is silently ignored.
With this fix, the attempt to mount a storage without strip alignment
setup on a super block will get an error with a warning in syslog to
indicate the true cause, e.g.
# mount -o sunit=4096,swidth=8192 /dev/sdb1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
.......
XFS (sdb1): cannot change alignment: superblock does not support data
alignment

xfs: Remove redundant error variable from xfs_growfs_data_private()
Commit eab4e633 "xfs: uncached buffer reads need to return an error".
Remove redundant error variable, using the function level error variable
to store bp->b_error instead.
