cifs: Fix parsing reparse point with native symlink in SMB1 non-UNICODE session

SMB1 NT_TRANSACT_IOCTL/FSCTL_GET_REPARSE_POINT even in non-UNICODE mode
returns reparse buffer in UNICODE/UTF-16 format.

This is because FSCTL_GET_REPARSE_POINT is NT-based IOCTL which does not
distinguish between 8-bit non-UNICODE and 16-bit UNICODE modes and its path
buffers are always encoded in UTF-16.

This change fixes reading of native symlinks in SMB1 when UNICODE session
is not active.
