Revert "nfs: pass flags to second superblock" 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBNEQX



--------------------------------

This reverts commit 81102eb5.

Since flags passed by users can not be set to fc->sb_flags, check of
fc->sb_flags in nfs_compare_mount_options is useless.
The second mount may get the superblock of the first mount since
nfs_compare_mount_options will return true, resulting the change of
s_flags.
Revert this patch and fix the origin issue later.
