ntfs: fix uninitialized variables in ntfs_ea_set_wsl_inode()

Browse Source 
Smatch reported uninitialized symbol warnings in ntfs_ea_set_wsl_inode()
and __ntfs_create(). In ntfs_ea_set_wsl_inode(), the err variable could be
returned without initialization if no flags are set and rdev is zero.
Additionally, ea_size might remain uninitialized from the caller's
perspective if no EA operations are performed. While these cases might not
be triggered under current logic, we initialize them to zero to satisfy
the static checker.
