    sysmobts: fix ph_data_req() msgb handling + alignment
    
    The way we recycle the msgb with a l1sap header when transforming a
    PH-DATA.req L1SAP primitive into a PHY/L1 primitive was flawed in
    several ways:
    
    1) the way the L1SAP header was stored in the buffer didn't provide
       sufficient tailroom for the L1 primitive
    2) the alignment of the data in L1SAP is at a 32bit bounadry, but not
       in the L1 primitive, causing unaligned accesses.
