NFS: Save struct inode * inside nfs_commit_info to clarify usage of i_lock

Browse Source 
Commit ea2cf22 created nfs_commit_info and saved &inode->i_lock inside
this NFS specific structure.  This obscures the usage of i_lock.
Instead, save struct inode * so later it's clear the spinlock taken is
i_lock.

Should be no functional change.
