Namjae Jeon d276bcc5f7 ksmbd: set fixed sector size to FS_SECTOR_SIZE_INFORMATION
[ Upstream commit 02655a70b7cc0f534531ee65fa72692f4d31a944 ]

Currently ksmbd is using ->f_bsize from vfs_statfs() as sector size.
If fat/exfat is a local share, ->f_bsize is a cluster size that is too
large to be used as a sector size. Sector sizes larger than 4K cause
problem occurs when mounting an iso file through windows client.

The error message can be obtained using Mount-DiskImage command,
 the error is:
"Mount-DiskImage : The sector size of the physical disk on which the
virtual disk resides is not supported."

This patch reports fixed 4KB sector size if ->s_blocksize is bigger
than 4KB.
