Fix for badness in remove_proc_entry

[Pavel Roskin]

Hello!

Hostap fails to remove /proc/net/hostap/wlan0, which results in a kernel
warning when it tries to remove /proc/net/hostap on module unload.

Badness in remove_proc_entry at fs/proc/generic.c:664
Call Trace:
 [<c016be5a>] remove_proc_entry+0x10a/0x170
 [<f8a39c1a>] hostap_exit+0x2a/0x6f [hostap]
 [<c012a76f>] sys_delete_module+0x11f/0x170
 [<c013d10e>] unmap_vma_list+0xe/0x20

 [<c013d500>] sys_munmap+0x40/0x70
 [<c0106fcb>] syscall_call+0x7/0xb

The reason is that the driver tries to free /proc/net/hostap/wifi0
instead.  The attached patch fixes this.
