CIFS: Remove __exit mark from cifs_exit_dns_resolver()

Remove the __exit mark from cifs_exit_dns_resolver() as it's called by the
module init routine in case of error, and so may have been discarded during
linkage.

[PATCH 2.6.32/stable] CIFS: Remove __exit mark from cifs_init_dns_resolver() header

[Michael Neuling]

An allmodconfig compile on ppc64 with 2.6.32.17 currently gives this error

fs/cifs/dns_resolve.h:27: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'cifs_init_dns_resolver'

This removes the __init from cifs_init_dns_resolver()

That's not really a good idea as the assembler may choose different pieces of
assembly to do variable references and jumps, depending on the section
information.

A better fix is to add:

	#include <linux/module.h>

to the header file.

Ok, new patch below.



CIFS: Fix compile error with __init in cifs_init_dns_resolver() definition

An allmodconfig compile on ppc64 with 2.6.32.17 currently gives this error

fs/cifs/dns_resolve.h:27: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'cifs_init_dns_resolver'

This adds the correct header file to fix this.
