    net/crc: reduce usage of static arrays
    
    This patch aims to combine the crc_xmm_shift_tab and shf_table
    into a single 32 byte array which offers similar functionality
    for left shift as well as partial_bytes shuffling.
    The first 16 bytes are now 0xff..0xf0 which behave identical to
    0xff..0xff when used as input to PSHUFB which will replace element by 0.
    
    Regarding the usage of shf_table in partial_bytes section,
    instead of xor with 0x80 of each byte, now we xor with 0xff and the
    table entries of crc_xmm_shift_tab is sufficient for this purpose.
    This allows us remove usage of mask3 array of 0x80 and replace it with
    _mm_set1_epi8(0xff) which compiles to single instruction "pcmpeqd XMM, XMM".
    
    As an example assuming remainder len is 5, we would have
    previously before this commit:
    temp = {0x85, 0x86, 0x87, 0x88, 0x89, 0x8a, 0x8b, 0x8c,
            0x8d, 0x8e, 0x8f, 0x00, 0x01, 0x02, 0x03, 0x04}
    After xor with 0x80:
    temp = {0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c,
            0x0d, 0x0e, 0x0f, 0x80, 0x81, 0x82, 0x83, 0x84}
    
    with the changes in this commit:
    temp = {0xfa, 0xf9, 0xf8, 0xf7, 0xf6, 0xf5, 0xf4, 0xf3,
            0xf2, 0xf1, 0xf0, 0x00, 0x01, 0x02, 0x03, 0x04}
    After xor with 0xff:
    temp = {0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c,
            0x0d, 0x0e, 0x0f, 0xff, 0xfe, 0xfd, 0xfc, 0xfb}
    
    Both the above pair of vectors behave same when used as input
    to PSHUFB (with MSB set bytes differing), thus achieving the same
    intended functionality.
