bug about Rate Match Conv

[Ruiming Lan]

In liblte_phy.h, the corresponding vectors may be better if they are defined as below -

// Rate Match Conv
uint8 rmc_sb_mat[LIBLTE_PHY_MAX_CODE_BLOCK_SIZE/LIBLTE_PHY_N_COLUMNS_RATE_MATCH][LIBLTE_PHY_N_COLUMNS_RATE_MATCH];
uint8 rmc_sb_perm_mat[LIBLTE_PHY_MAX_CODE_BLOCK_SIZE/LIBLTE_PHY_N_COLUMNS_RATE_MATCH][LIBLTE_PHY_N_COLUMNS_RATE_MATCH];

// Rate Unatch Conv
float ruc_sb_mat[LIBLTE_PHY_MAX_CODE_BLOCK_SIZE/LIBLTE_PHY_N_COLUMNS_RATE_MATCH][LIBLTE_PHY_N_COLUMNS_RATE_MATCH];
float ruc_sb_perm_mat[LIBLTE_PHY_MAX_CODE_BLOCK_SIZE/LIBLTE_PHY_N_COLUMNS_RATE_MATCH][LIBLTE_PHY_N_COLUMNS_RATE_MATCH];

Thanks Ben for the excellent job！
