[PATCH 10/13] target/riscv/insn_trans/trans_rvv.c.inc: use 'vlenb' in MAXSZ()

[Daniel Henrique Barboza]

MAXSZ() returns the value in bytes. Now that we have access to vlenb
we don't need to compensate with a '-3' in the scale to use 'vlen'.

MAXSZ() now works as follows:

LMUL  lmul=scale  MAXSZ (vlenb >> -scale)
  1       0       vlenb
  2       1       vlenb << 1
  4       2       vlenb << 2
  8       3       vlenb << 3
1/8      -3       vlenb >> 3
1/4      -2       vlenb >> 2
1/2      -1       vlenb >> 1
