nfs: fix the loss of superblock's initialized flags 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB42W1



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

Commit 81102eb5 ("nfs: pass flags to second superblock") directly
assigns fc->sb_flags to dentry->d_sb->s_flags, which will cause the loss
of the initialized flags in dentry->d_sb->s_flags.

Fix it by just passing SB_RDONLY from fc->sb_flags to
dentry->d_sb->s_flags.
