[PATCH] smb: client: use GFP_KERNEL for registry allocation

From: Fredric Cover <[email protected]>

Currently, cifs_get_swn_reg() allocates new registry entries using
GFP_ATOMIC. Since we lock a mutex here, this is clearly not an atomic
context. Use GFP_KERNEL instead.

Also, fix a minor grammatical error in the comment above the function.
