qcacmn: Increase the field width of bandwidth for 320 MHz

The current field width for bandwidth parsed from
tx completion status is only 2-bits, which is not
sufficient for 320 MHz and 240 MHz, since these enum
values are 4 and 5 respectively,  which needs a
minimum field width of 3-bits to store.

Increase the field width of bandwidth in the tx
completion status data structure to account for
320 MHz and 240 MHz enum values.
