proc: no need to initialize proc_inode->fd in proc_get_inode()

proc_get_inode() obtains the inode via a call to iget_locked().
iget_locked() calls alloc_inode() which will call proc_alloc_inode() which
clears proc_inode.fd, so there is no need to clear this field in
proc_get_inode().

If iget_locked() instead found the inode via find_inode_fast(), that inode
will not have I_NEW set so this change has no effect.
