staging: erofs: return the error value if fill_inline_data() fails

Browse Source 
We should consider the error returned by fill_inline_data() when filling
last page in fill_inode(). If not getting inode will be successful even
though last page is bad. That is illogical. Also change -EAGAIN to 0 in
fill_inline_data() to stand for successful filling.
