[PATCH] nfs: fix do_div() warning by instead using sector_div()

[Helge Deller]

When compiling a 32bit kernel with CONFIG_LBDAF=n the compiler complains like
shown below.  Fix this warning by instead using sector_div() which is provided
by the kernel.h header file.
 
fs/nfs/blocklayout/extents.c: In function ânormalizeâ:
include/asm-generic/div64.h:43:28: warning: comparison of distinct pointer types lacks a cast [enabled by default]
fs/nfs/blocklayout/extents.c:47:13: note: in expansion of macro âdo_divâ
nfs/blocklayout/extents.c:47:2: warning: right shift count >= width of type [enabled by default]
fs/nfs/blocklayout/extents.c:47:2: warning: passing argument 1 of â__div64_32â from incompatible pointer type [enabled by default]
include/asm-generic/div64.h:35:17: note: expected âuint64_t *â but argument is of type âsector_t *â
 extern uint32_t __div64_32(uint64_t *dividend, uint32_t divisor);
