6ef2abe80e igzip: fix issues reported by static code analysis 
compute_dist_code() and compute_dist_icf_code() in huffman.h:
    Correct `assert(msb >= 1)` to `assert(msb >= 2)`.
    `msb` cannot be lower than 2 as it would result in corrupt computations.

get_dist_code() in huffman.h:
    Remove dead `if` statement at the beginning of the function.
    `dist` must be equal 1 or above in this function.

abd80d3c5a erasure_code: check for size in gf_Xvect_mad_avx512_gfni 
Length of data was not checked in implementation with AVX512+GFNI,
at the start of the gf_Xvect_mad_avx512_gfni functions, resulting
in buffer overflow if length was less than 64 bytes.
