cxgb4: Allocate dynamic mem. for egress and ingress queue maps QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END. For eg, in the first load eqid can be from 100 to 300. In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is 1000). The driver was assuming them to always start from EQ(IQFLINT)_START till MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash. Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for these structures.
